Whats the first mod that you would suggest for a 305 tbi w/ a T-5
Ok, I take that you read the subject when you clicked to get in here, so...i want to get something bad***. I can't afford heads, so lets not discuss them. The mod doesn't have to add tons of power but I just want something cool to start on. Thanks for the suggestions. big tex

Flowmasters? you got 2? how's that 
? Get a flat based open element air cleaner. The air cleaner snorkel chokes the engine to death. its only about 1"x2". After you get the exaust and intake flowing a bit you can upgrade the ignition. (I haven't done this yet so I dunno how much it helps). You can get 1.6 ratio rockers too...

I agree with the above posts. Open element air cleaner ( shown on this site in the tech section) and 3.42 posi gears for your t-5.
You can get a torsen posi take off unit from
SLP cheap. don't forget you will have to change speedo gears which is a major project on a T-5........bob

not closing, but please search and read the archives in before and then in conjunction of posting, it will teach you a lot and answer most of your questions, then all you have to do is ask about the stuff you cant learn from there. Thanks, snflupigus

dont worry about speedo gears If u switch rear end gears. If u dont change them the only thing that will happen is ur speedo will read like 7 MPH faster than ur acctually going.

Yeah you can run with with out changing speedo gears, I did for a long time but depending on what gear ratio you select you will be between 5 and 10% faster on the speedo than actual. That goes for the odometer too, so you gotta figure if its worth it. You can always do it later.There is a ton of stuff on this in the archives.......bob

you said you dont have alot of money gears cost some cash especially the labor you can usually find gears used at camaroz28.com first mod real cheap mod you will like is the simple op0en element air cleaner cheap and easy. you'll like it! then do the gears and posi.

Actually, what gear ratio does he have now? If its 2:73's and he switches to 3:73's or 3:42's then it will be off by more like 15-20mph. And that ain't cool when ur racing someone with that speedo limiter. Cause it will think your going 110mph when actually ur only going 85mph and then it shuts down ur car at 85 instead of 110. If you do the gears. Make sure u get your speedo recalibrated. I know of plenty of times when I was racing and I had to hope that I would beat the person by a car length so when 85mph hit I could get over in their lane and just claim the V before they flew by past 85mph.

I know man. It sucks big time. I am waiting to do mine since I am getting 16x8 rims soon and different tires. So no sense on wasting money doing it now when it will have to be done again in 2 months. Its not that bad I guess. I mean, when do u go 85mph all the time? I usually have a 55mph road to travel on and thats it. So it hasn't been that bad, but racing sucks with it. (like I said above)

thanks for the info on the gears...but earlier on this post, someone said it was a real b*tch to recal the speedo gears. What makes it so much harder on a manual than it is on a auto. By the way 91bird305...I love your site, it has been extremely helpful.

305 bird, Good point on the speed limiter/speedo gears issue. I never thought of that so I am really glad I did it, even if in a state of ignorance.Tex, The t-5 has a drive and driven speedo gear.( check archives) to get to the Drive? gear you gotta get inside the trannie, which means the tail shaft housing has to come off. I had the work done by a friend who is a 30 year Chev dealer Tech so I don't totally understand it and maybe someone knows an easy way to do it.I have heard on this site that it is much easier to recalibrate speedo on an auto. There is a tech article on this site I think regarding the auto, but I have never seen anything
on how to do it on a t-5 . Might want to pick up the correct manual.Good luck............bob

<font face="Verdana, Arial" size="2">Q: How to I calibrate my speedometer for new rear-end gears?
A: Determining the precise speedometer drive gear/driven gear combination required for a rear axle ratio change is surprisingly easy-if you know the existing combination and axle ratio. Whip out your calculator and follow along. Let's assume that your F-Body is currently equipped with 2.73 gears and that you're planning to install a 3.73 ring and pinion. If you didn't change speedometer gears, actual vehicle speed would 73.1 percent of indicated speed (2.73/3.73 = .731). That being the case, what's required is speedometer gearing that will result in the driven gear spinning at 73.1 percent of its current speed. The speedo gear combination for a 2.73 rear (assuming 26-inch diameter tires) is a 17-tooth drive gear and 37-tooth driven gear. Switching to a 45-tooth driven gear (the most teeth available) would translate to the vehicle traveling at 82 percent of indicated speed - still a 10 percent error.
Obviously, the drive gear must be changed to one with 15 teeth if the 73.1 percent ratio is to be achieved. Going back to the original 37-tooth driven gear for illustration purposes, the 15-tooth drive gear would result in the vehicle traveling at 88 percent of indicated speed - that seems like a step in the wrong direction, until the driven gear is changed. (This is where it gets a little tricky because you have to work with a percentage of a percentage). Matching the 15-tooth drive speedometer gear up with a 44-tooth driven gear brings the drive ratio to 74 percent (15/17=.88; 37/44=.84; .88 x .84 = .739, which rounds to .74, or 74 percent). Still not quite enough. Will a 45-tooth driven gear do the job? Run the numbers through your calculator and you should come up with 72 percent. That's about as close as you're going to get.
In case you haven't put all the pieces together, there is a distinct limitation regarding speedometer accuracy and steep rear gearing. Unless driven gears with more than 45 teeth, and/or drive gears with fewer than 15 teeth become available, it will be impossible to have an accurate speedometer with rearend gear ratios lower (higher numerically) than 3.75:1 - unless 27-inch or larger tires are installed.
Q: I want to buy speedometer drive/driven gears, what are the part numbers and combinations?
A: Here is a list of GM part numbers for drive and driven speedometer gears, as well as some combinations that are known to work:
Part No. Teeth Color Sleeve*
25513042 35 Orange 25007338
25513043 36 White 25007338
25513044 37 Red 25007338
25513045 38 Blue 25007338
25513046 39 Brown 25007338
25513047 40 Black 25007339
25513048 41 Yello 25007339
25513049 42 Green 25007339
25513050 43 Purple 25007339
25513051 44 Dk Gray 25007339
25513052 45 Lt Blue 25007339
*Some applications may use Sleeve No. 25007224 or 10456092 in place of 25007338, or 25007308 or 1045089 in place of 25007339.
Red Drive Gear Combinations
With drive gear number 8640517, (red, 17 teeth) the following combinations apply:
Axle Tire Dia. Driven Gear
Ratio (Nominal) (Tooth Count)
2.59 26.0 35
25.7 36
2.73 26.0 37
25.7 38
2.87 26.0 39
3.07 26.0 42
3.31 26.0 45
Gray Drive Gear Combinations
With drive gear number 8642620, (gray, 15 teeth) the following combinations apply:
Axle Tire Dia. Driven Gear
Ratio (Nominal) (Tooth Count)
3.33 25.7 40
3.45 25.7 41
3.54 26.0 42
25.7 43
Lower ratio (higher numerically) rear or smaller diameter tire requires higher driven gear tooth count. Increasing or decreasing driven gear tooth count by one will usually accommodate a 1/4" to 1/2" change in tire diameter.</font>

damn eric sure answered that one
as for ur current set up. U have a 3.08 open (possibly posi) rear end. If u go with a 3.73 gear ur speedo will be off about 7 mph. Thats what the guy who did my rear end told me. U should be able to do about 105 to 110 MPH before cutting off. It might be different in auto cars due to the fact that t 5s have a longer 5th gear ratio.

jprevost ur right. I had 3.73 gears installed and they arent stock. While the car is stock i felt gears where a good mod that no one would ever notice that would make my car quite a bit faster. I am just not into extensiv mods that kill resale value. Gears arent one of them. U know what i mean?

i dont worry about resale value, i never ever plan selling my car. 
sorry, just had to add that
gears would probably up the value, because it would only impress somebody, and they dont even have to know.

I hear you on the resale value but my car has been totaled already by some drug rehab rejects so there you go. Don't you want to have fun with your car? I mean it's not like it's a Caddy or a station wagon. It's a f-body, they are street machines that need to be run hard every once in a while. Why would you have bought the car in the first place? Don't take this the wrong way but are you like those guys that own 3 really old cars and never drive them until a local show comes up? That last line shouldn't be taken seriously.

Hehehe, I don't know how much of a resale value of a car that was produced 32,376 different times in that year. I can see if it was maybe a formula and you were keeping it the rest of your life (the formula) but as I see it. I don't think there going to be showing the LO3 Firebird on My Classic Car in the future. So I will just make mine as fast as hell so I can then put it on my classic car just because its old and f_cking fast. Hehe

I agree with Eric. If you want to make a sound financial investment, start an IRA, don't buy an F-body. I have my car for entertainment. It's a hobby and hobbies cost money. I'm confident the sum of the mods I have done have not lowered the value of the car at all. But really I don't care, because I didn't buy it 10 years ago with the intention of selling it and making more money. I bought it to have fun. It's just a toy, and toys cost money.

well everyones deffinition of fun is different. LIke to some people a run to the local strip is fun. Too me kicking back on a nice sunny afternoon and washing my ride and polishing it is my kind of fun. Letting it sit looking fine as can be not moving at all just so when people go past my house they see my car and stare. Its not so much driving that car its just the self gratification i have owning it.

8T9...just a question...I have been wondering about why you come to this board if you have no intentions of modding or anything. I don't know...maybe a dumb question thats going to get a response that will make me feel like a retard Just wondering....

well the biggest reason i come on these boards is to help people and relate. Its easy to relate to people with the same type of car as me. I also like to learn something hear and there. Just look at it like this. pretend these boards are school and u have 2 groups of people or "clicks" as some might call it. U have the OEM guys and the Modded guys. see what i mean?

and the oem guys are the ones the modded guys make fun of. so the oem guys get mad and go into the school shooting. ok, bad joke. But really, i think i would say the "popular" people are the modded group. Not saying either is better. But as you know, as in the real world, majority rule. and as an oem guy, you gotta know that your gona catch flack and people are gona try and assimilate you into their "cool" group to help you out. Either that or they will just crap on you all day.
btw, in hs, i was one of the modded people.

snflupigus u bring a very good point about there being alot more guys who mod as opposed to the OEM guys. Thats what makes a mint condition 3rd gen rare in stock form becouse there is so many people modding them. Thats what makes mine stand out around here
BTW eric its just about as hard if not harder to bring a carn back to OEM rather than mod it. But i guess that can go both ways if ya really think about it so NVM

It's worth more..lol. Not right now it isn't. Blue book maybe but that doesn't count in real life. It's a book. People pay for what they get. The major market for the f-body are young males that don't give a rats *** if it's stock. In fact if it's stock they'll probably pass on it because it's not very fast and the seller is asking too much (in their eyes). It's like my grandmother says all the time: it's only worth how much others will pay for it. I like the comment about getting an IRA, not an f-body. Makes sence. Oh well, still, I have respect for people that don't want to change much on there f-body. Just look at the first gen camaro's with all OEM parts. It's great and that's for the old pharts in my opinion (no offense towards memeber 
ldphart). I know one day I'll be like that but I'll be the white haired flame spitting 91 RS with a double blower setup and crazy mods. Lawn chairs in the custom made trailor that matches the car.

Hehehe, J you need to come to Woodward Dream Cruise with all of us. Your future self is all over at that time (old guys with fast as **** cars)
Honestly though, compare a modified car to a totally stock car. Obviously there is more money put into the modified car so why would the stocker be worth more? Thats like saying, if I drop a modified 350 in my car that someone stock 305 firebird from that year is worth more. That just don't make any sense to me. Personally, I love OEM guys. They are the most fun to play with on the street.

OEM is worth more becouse people who know want a car thats been untouched and :fresh" so to speak. Eric if u dont know why OEM is worth more than modded than i am really not gonna get into it. I just dont really care to. If ur stock car cant beet a modded car than just get a faster OEM car. Its real funny when the modded to all hell guys get beat by a stock LT1. So much for OEM being the hunted Just an exapmle

Well, I guess I straddle boths sides of the fence on this one. I have a 69 Firebird that has only 89,000 miles and it is totally original, engine, all body parts, tranny, rearend, everything. I even have the very first 69' license plates.The only thing that wasn't original were the wheels, and I've since then found a whole set of 14X7 Rallye II's and now everything is back the way it came. I've always had an overwelming desire to make it a fire-breathing street machine, but due to the fear that I will decrease the value, I've just decided to keep the car under shelter and let it increase in value and maybe one day, do a total restoration. On the other other hand I got my 2 Camaros. I got the 82 Z when I was 16 and not much at all is original on it. The engine, tranny, and rearend are long gone. The interior has completely been replaced with various years' peices and a lot of aftermarket peices, e.g. steering wheel, seats, tach/gauges, shifter, cage, etc. The hood has been replaced with a Harwood and I recently bought a whole set of 92 Z28 ground FX and rear wing that I am going to put on the car. The car is much faster, and in my opinion looks much better inside and out than any stock 82 Z28 did. It definely turns more heads than a stock run of the mill Z28. Then there is my 89 RS. enough said its an 89 RS, its nothing special, its about one step over the a base Camaro and the mods I've done to the car has got me offers to sell higher than what any stock 89 RS I've seen going for. I bought it to drive on the street since my 82 sees VERY little street duty, but the stock L03 was just not as fun to drive as I wanted, so I decided to do some mods to make it perform better, and look better. I've put on IROC wheels, IROC foglight grille, and 92 tailights. I am going to buy either a cowl hood or the 4th gen style SS hood and have the car painted. I am leaving all the power and luxury accessories on the car such as the air, cruise, pw, pdl, but I am in the process of changing over the suspension to all IROC stuff that I am robbing off of a parts car. I installed the wonderbar, the front hollow sway bar, and polyurethane end link bushings this weekend. So I guess I'm a OEM guy and a modder!!
BTW, My modded car cars are more fun!!

Hehehe, well lets see. LT1 vs. LO3? Yeah, I know my chances are slim. 305 vs. 350? Yeah, chances are slim again. But thats not anything a 350 can't fix that I can throw in. And a modified 350 at that. Wasting our time? I doubt it, modding is learning about your engine and enjoying owning a V8. If I wanted to p_ssyfoot around all day in something then I would have bought a small economy car (which I will never own). Your suppose to have fun with these engines, thats what they were made for. Go race people on the street, have fun. I don't ever plan on selling my 91 Firebird, it will always have new 350 in it when the 305 goes, new pro-built tranny if that goes and a new rear end if that ever goes. So value doesn't mean squat to me really. As long as the car look spectacular on the outside still and I get looks and compliments and my engine still hauls ballz. But hey, OEM have to have fun too i guess and keeping it stock and racing other "stock" cars is fun I guess.

I like waxing it, not driving it and a new dealer part here and there. To me my little 3.73 geard 5 spd L03 is enough fun for me and if its not i have a HO TPI car sittin in my driveway. Its always fun to have another

well, I bought my unmodded 92 RS with 47,000 miles on it last April from this old man for 5000 bucks it was worth probably 7500 or a little more, but then there was another 92 with 91,000 miles on it and they wanted 13,500 bucks...I was thinking hell no, i'm not paying that much but I looked under the hood and there was a LT1 with new cam,nitrous, and headers. The car was apparently bad *** and worth a hell of a lot more than the unmodded one I ended buying. bigtex

lol, I think I got the best deal next to that guy that just picked up his 91 bird for $750. But he still put body work into her since it came with a messed up front end. Okay, here it is: back in 98 I picked up the big red with 143K miles on her, all highway because it was used as a daily driver to and from work in NYC (lived in mid NJ). The car had been through 5 owners before me (car fax). The thing ran real strong, guy told me he'll through in the SLP headers, he was asking $4750. Let's just say I got everything and for only $3750, centerline 16x8's too. Too this day my friends wish they had gotten sports cars. Every one of them hates having to drive there "sedans" into the city while I get to do the local and beach cruises. Just now are they getting rid of there rides for vehicles with more road pep. Example: 98 RAM ex-cab long bed for a 2001 jetta 1.8T custom chip, real quick; 98 4.0L wrangler seirra, wants a sports car but stuck in a 6 year finance; 94 jeep cher for a 96 maxima; other friend has a 69 maro; another is on his second 2nd gen taurus 220hp SHO. So far the conversions have been real smooth, next is my dad, gotta get him off the suburban thing and into a camaro.

BIGTEX becouse the guy is trying to get to much for a car doesnt mean its worth that much. I bet if u go look today he still has the car or sold it for way less than what he wanted. No one knows the quality of his motor job so how would he be able to justify such a high price, i dont know. Another point though. go look at that car in 10 years and go look at the same car only factory origional with low miles. THe OEM car will be worth alot more...

actually the guy who was selling the car owned a local performance shop and apparently he was selling his most recent project. I see the car everyonce and a while. Some old guy is driving it.

ok eric ill explain this very carefully. U have a low mileage third gen with everything origional and in mint condition. Next to that u have a modded to all hell third gen with a 9 inch rear, an LT1 and a 200 shot of nos(just an example). When u mod a car it no longer has its collectability therefore making the origional car worth more. I am sure u heard people say "u never get what u put into them". That goes for modded cars. Notice how u put alot of money into them and u wont get it back from them. Think about it, typically a guy who mods his car goes fast alot. In other words he beats on his car. No one wants a rigged up beat on car. Simple as that. If the LT1 where in say a 94 trans am and it was OEM than that would be a different story but its not. There fore making the factory thirdgen worth more than the LT1 modded thirdgen. Just look in ur local auto trader and u will see what i mean.
