the other one got locked which is stupid, as i stated i was not drinkin much but half a beer if that, woopidy dooooo, i dont drink and drive, not after i lost 5 friends in a car wreck cause they were all drunk, just dont close this thread, i went to genes muffler located out here in missouri, where i got my exhaust at, they said its pushin near 350 hp, believe it or not, i plan on goin the the highschool drag races, to get time slips, and see what it runs in the quarter, also, where is the vin # on the motor?? i wanna find out what i can bout it,


PS... DONT DRINK AND DRIVE, i've lost too many friends that way, its a bad decision, i didnt make my self clear in the last thread, sorry about that

 

Do you have a blower or something? im not saying 350 hp is not possible with a 305, i know its is, but thats a SHIAT load, you must have LOTS of mods. The HO 305 only had 190...what kinda stuff do you have done? and if you are talking about racing a Lt1, you better have serious mods. How did he know you where around 350 ponies?

 

Just read the other post. Yeah his lt1 must have been crappy, or he couldnt drive, or you have serious mods, id think.

 

I am still calling I still think you have a 350 or 383. I am not taking the victory away from you and calling BS on that, but something is not right. You need to find out what mods you have, what kind of tuning you have to handle 350 HP (must be the best PROM burner everto make 350 on a 305 drivable). Do you have a pic of your engine? Even if your 305 is built to all hell your TPI set up must be ported to the farthest extreems. How does your car idle, how is your low end? That will give you a clue on how big your cam/stall is.

 

I didn't read the other post, but what's so hard to believe about a 305 beating a high 13/low 14 second car? It can be done. I believe it.

 

heres a pic, u all dont have to believe me, i really dont care, i'll show u time slips to prove when i go to the drags

 

As stated before I am not doubting the win I am doubting his power output. From that pic it looks like he is still running the stock exhaust manifolds. You will not get 350Hp out of stock exhaust manifolds. No way.

 

So the muffler shop has a dyno? You don't have to show us time slips, show us the dyno log, or was the "muffler" shop just guessing the hp. If they just guessed , then this is pointless.
And I agree 350hp out of stock manifolds is bs.

You will barely run away from an LT1 with 300hp. Most LT1's are rated at 275 but put out about 295 at the fly or 255-260 at the wheels.

 

... in a lighter car.. yea.. 300hp will cary him faster then a 200-400lb heavier car... My car, which also is an 87, weighs about 3550 with me in it, and im 240. My car is fully loaded with AC, and power everything. LT1's average about 3400-3600 depending on what model and what comes with it. a 300hp third gen will put beat out a stock LT1

 

A thirdgen with an LT1 will beat a 4th gen with an LT1 and that is my point. He said the LT1 was in a thirdgen if I am not mistaken. I think he said an 87 Bird. So that makes it seem even more far fetched.

 

no it doesnt...if his 305 is still making more power then wtf? he won... i dont see the problem... 305's CAN make power.. maybe not 350rwhp, but 320fly wheel could be done i guess with a good build up, cam and heads...

 

im goin the highschool drags next week if its goin on next week, then i will get time slips, well scott at genes who rebuilds cars he guessed, so i dont know, i dont have dyno slips, where do i get them?

 

I geuss he will have to prove us dissbelievers wrong. That Thirgen with the LT1 should be a mid to low 13 second car. If he is beating that by a lot he would have the fastest N/A non-header 305 that I have seen.

bigals87z28,

Yes you can get 320hp out of a 305 but it takes a lot of money, experienced PROM tuning, traction, huge cam, and more importantly headers, of which his car does not have. You WILL NOT make 300hp on a 305 without headers. And if he had a cam that got him 300hp without headers his power curve would be so steep any other v-8 powered car would kill it off the line until he wound it up and made the pass.

I am really not trying to be mean here guys. I have raced a full bolt on heads and cam and tuning 305 and it was no contest. And I was in a car that weighs a lot more than a thirdgen. Put that same powerplant in a thirdgen and it would get ugly.

 

I don't wanna rain on anybody's parade but lets be real here! I used to have a 305 TPI LB9 in my '87 Iroc. Yes over 300 hp is attainable with alot of mods. And with a 5 speed it gave any stock LT1 a run, but if that 305 pictured above is the puppy we are talking about.....forget it! I think we all know enough to say that 350 hp out of that thing is rediculous! Stock intake manifold and exhaust, you'll be lucky pumping 215 hp out of that thing. And to talk about taking on an LT1? Don't even think about it!

 

Where do you get a dyno sheet??? Did you ask that? You cant just get dyno sheets online, you have to have the car dynoed! That requires going to a shop which has a dyno (whether dynojet or Mustang dyno) and having it put on and run! Then you get the printout of the sheet and it tells you the story of what power you make and where you make it!

 

Finally some guys here are backing me up

 

What's there to back up? I mean whoopty frickin doo. He beat an LT1. They aren't that fast. Maybe high 13's on a good day. Lots of 305's have surpassed that.

 

I am talking about the guys that are calling BS on HIS setup, not that a fully worked 305 couldn't beat him. I do not belive that there are many 305's running solid 13's N/A. With spray and or supercharger sure it can be done. An LT1 in a thirdgen is a serious car and is capable of low 13's any day of the week. Look over at camaro z28.com and some 4th gen guys are running 13.5 with an intake only. Put that motor in a 300 lbs less car and it would scream. If he had full bolt ons and heads and cam I would believe it to an extent. Look at that picture. No way a non header 305 (regarudless of internals) is going to beat a thirdgen with an LT1 (unless it is not really an LT1). Even if the LT1 swap had the stock thirdgen exhaust it would still be slightly faster than the 305.

And yes LT1's aren't that fast when you compare them to LS1's or any other built 350. That is not my argument here. But a suposedly "built" 305 with STOCK EXHAUST is no match for an LT1. Like I said in previous posts. I have driven and raced a full bolt on (I mean everything) heads and cammed 305 with custom PROM and it was no match. By the time I hit third I pulled many many car lengths. This was in a car that weighs 300 lbs more too mind you.

 

Yeah I too agree. Sounds a little fishy to me but who am I to complain, I have never raced a fast 305 or a thirdgen with an LT1 so I dontk know either ones capabilities!

 

Alright... after reviewing the engine pic (which i dont think i saw before) Dude, better show us some slips or dyno sheets because im gunna start to raise the bs flag. Your intake look stock, heads look like they havent been touched, no headers... Im with the other guys... Im sorry for the fighting... I guess i was just defending the 305... but this guy pushing out 300 in that... nitrous is all im saying... wheres the plate...

 

hey i have a 305 tpi and i have slp headers 1 3/4 pris and no cat and only ran a 14.3. i have seen stock 305's with a stall on them run a 13.9. so if u think about it its not that hard but it doesnt look like u have anything done to your car so i mean a 75 shot and a cam with a stall could easly beat a lt1 but it doesnt look like u have any of that so im sayin . sry i need to see some slips or dyno. Brcyon

 

i have no clue it may be bull****, genes mufflers put on the headers and the dude said i bet that thing is pushin near 350 horses, just from how it sounds, i just wanna know where to get it dynoed, do i go to like a sound by extremes, i heard they dyno cars and do that spl ****, but if any of u lived around here, u'd be pretty shocked what my car can do, maybe i can get a video of it?? i can do that, but idk how to put them on this sight, im gonna take it to genes sometime again, and see if they can get it dynoed, and i guess ask them why the hell they said 350, cause when i think bout it again that kinda does sound weird, cause since these 305's came out with what 215 with the tpi setup??? and i k now im pushin a lot more than stock, cause i can smoke 305s so bad its not even funny, i'll have more info later,

 

k i know what u are saying i can beat 5.0 to but pushin 350 hp i dont know man we came with 215 stock with the tpi so i mean u would have to do alot to be pushing 350 again it wouldnt be hard i beleave u can stall and nos and cam do u have any of that? i guess i dont doubt u i have no reason to so i just want to see some slips. brycon

 

haha, i just saw someone say my engine hasnt been touched? huh, i have receipts every from the rebiuld, i'll copy everything they said, another of my friend has a camaro newer one, 4th gen, and the damn thing has the lt4 kit, well lets just say mine wont even touch that, that sucker is fast, how much hp will the lt4 kits get u?

 

Whooooa! Check out my 305 dude!! Wacka wacka wacka LOL

 

OK it sounds like 350hp. Well then jee wiz I didn't read that the first time through . My race lawnmower has a straight pipe on it and sounds nasty, maybe I've got 50 HP out of that then.

My El Camino sounds like it has about 700HP (love turbo wine ) But I'm not ignorant enough to beleive that.

I wish I was still young and full of **** and vinegar and had an N/A 305 with stock manifolds and no juice pushing 350HP (OH yea I know why because a build like that would cost over $5000).

OK let me get telepathic, you bought your car from a guy in his mid to late 20's that said he had the engine professionally rebuilt and had the receipts but lost them, he then rattled off a bunch of performance parts that were put in the car. You then went home and looked all the parts up on the internet and started drooling and then went back and bought the car.

Well Reailty Check Anyone who builds a 320HP N/A 305 doesn't leave the stock exhaust on it.

Later, Garrett

 

this forum sucks, i made myself clear i do not have the stock exhaust, and i have headers, so **** off

 

DID ANYONE ELSE READ THIS!! SPL! ahahah! thats with systems! holy chit kid... where did you come from... No... a dyno or dynomometer measures HP, not sound... wow man... you are something else... I was backing you up till you just proved to me that you dont know much. A dyno will measure hp at the wheels or you can have your engine dyno'ed to see what it puts out at the wheels. Only a few shops have a dyno because they are a pretty penny. Most if not all hi-po shops should have one. TPI does give you great power and I agree if someone was in my car for the first 3k rpm, it would feel like my car would have 300hp.... but I assure you it has about 220 fly wheel hp at the most. Dont confuse torque with hp. Someone at Midas thought my car had a big block because the way it jerks foward when you push the accelerator down... I gave him the stink eye. SPL is for ******* who think systems are cool and 40 15in speakers make there car da chit... Want a system?... get a blown 454 big block with dumps... Lets see your rebuild sheet and see what they did to this thing. I must say, a TC, gears, and other mods might not add hp... but they will improve times at the track.

also, i must add that the engine dyno and a chassis dyno will produce different numbers due to drive train loss.. ALL hp ratings you see in the mags are of net engine hp as of 73. Before then it was gross engine power, that means without accesories on it... just the engine.

 

I understand that you don't have stock manifolds anymore. But in the pic's you did and you just got headers installed. But your headers added 30HP tops so if you have 350 HP now minus the 30 gain for the headers and your looking at a 320HP stock exhaust manifold TPI 305, which is highly doubtful.

om ****in ***, i was sayin that this place in sedalia sound by extremes dynoes HP and and they do spl and some **** like that, **** this forum

 

sorry im gettin so mouthy, its just i hate people bein jack A**es, it sucks, i know a lot about cars, i really do, just not really enginees and ****, just like body crap and stuff like that, go ahead, make fun of me all u want,

 

sorry for making fun of you. Im gunna go out on a limb here and say that the music shop doesn not have an engine dyno, but a room that measures your system. This has become a popular along with "drag racing" systems... dyno testing and drag racing systems is a mockery of the hot rod.

 

o, now i feel really stupid, lol, my friend prolly was bull****tin me on that ****, well **** i have a brain of a pea about cars then, where do i learn **** bout them, lol, i do know one thing, i change my own oil, lmao, i'll get the reciepts, for the whole rebuild on the reciepts it adds up to only like 1700 which prolly isnt much is it?? maybe the guy at genes said 250, idk tho, i just cant believe i beat the lt1, but u have to also consider, the guy had the stock rearend from a z28

 

To reach 350HP on a 305 requires alot of work. Cam, heads everything else. To outrun a stock LT1 you only need gears, exhaust, stall and some work on the TPI system and you should be able to do that.

What we are having a problem with I think is the whole 350HP out of a stock looking manifold crippled 305TPI having 350HP AND beating a LT1 in a thirdgen.

It does sound far fetched to me. Not that he beat an LT1 so much. He could have beaten the LT1 equipped thirdgen if the guy couldn't drive, if his setup wasn't tuned, or he had some technical problem. What I can't believe is a 305 with stock exhaust manifolds pushing 350 HP.

 

umm well this place is a great place to lean about third gens... AND NOTHING ELSE!! I sugest to learn more about other cars is to read mags. Popular Hot Rodding, Super Chevy, GM High Tech,.. all the mags except for import and hot rod as they are now into the whole import scene which is sad to see a great mag really looking for new readers... its not gunna happen because import **** are still gunna read that soft core **** they call a tunner mag, and hot rodders and muscle heads arent gunna read HR because its got imports in it. I think there gunna lose a lot of members. Hope they snap out of it like they did in the 80's and 90's. now there going back to it... wtf. anyway, as i digress

I sugest going to barns and noble, grab a nice cup of white moca late(its good.. tastes like vanilla ice cream coffe) and sit down with a couple of car mags and read away. I do it almost every weekend... Read into cars, mods, other cars and what you are going up against... also its a good idea to read the bigger mags like car and driver, road and track, etc to see whats coming out from all the companies... its an exciting time to be a car nut as ther are HP wars happening again. Look around you, everyone is building faster, quicker, sweeter looking cars. And the best part is the most of them are RWD.

Ok now that this is totaly off topic, Ill try to recenter it. Where did your friend get the LT1 out of? What were you talking abotu having the stock Z28 rear? do you have a bigger/stronge rear? 1700 for a 305 is...well... i dont know.. if you have crap parts put in, you got ripped on labor, but if you had forged parts put in, and your car is built like a brick chit house, then i say 1700 is pretty good considering how hard it is to find strong 305 parts. Then there is always the thought that you beat the driver, not the car.. but i think thats just some ri-cer excuse IMO. ok i think im done for now...

 

lmao ya i know i was just saying it wasnt that hard to beat one with a stock manifold and with all that other stuff he could run at least 13.2 or lower thats all i was sayin :lala:

 

i have 3.7? gears, got it from a junk yard when mine went out,

 

Ya, I'm not doubting the fact that you beat an LT-1 Thirdgen. I was doubting and calling BS on the 350 HP 305. Sorry if I offended you but I wanted to make it obvious that I disagreed with the comments you made about the 305.

Later, Garrett

 

 

i will never underestimate good 305 's anymore , i own a 86 305 tpi trans am with 27, 000 original miles on it , last weekend a young kid with a 87 350 tpi called me on he had 100,000 miles on the car , the only mods i have on the ta is 3.42 gears , cai , airfoil, 8.8 m wire, splitfireplugs , b&m shift kit,

well we went from a 60 kilometers and i beet him by 3 car lengths so 305 tpi are decent cars
