I got some cash (finally) to play with. Right now all I have is dual exit flowmaster muffler. I wanna go: headers and dual cats heads,cam, and intake posi and gears chip pullies?? aluminum driveshaft??

You could do all that and supercharge the thing with enough $$$ left over to fill up your gas tank and buy a happy meal.

For *** sakes, do this.

Don't WASTE 4000 bucks on that 305. Do this swap and get yourself some real power and real potential for later on down the road. And those numbers aren't "estimates" either. So that is actually how much everything would cost, so thats including the extras. Now you got urself a kick a$$ 350 HO motor with a sh*t load more power and potential then u would ever get from ur 305 for 4,000 bucks.

sonds liek a good list to me, i woudl bag the pullies adn add a extra set of rear wheels with some drag tires, boxed/tubular control arms, control arm relo brackets, adn maybe a good torque arm(look at the spohn ad at the top of the page) if you have enough money left over.
scoggins-dickey has stock LT4 cams for $180. www.sdpc2000.com

you could be flyin
good luck

later
tim

your in California though, Emissions is gonna get you if you are not careful. I say start with a nice shortblock and build a good emissions legal motor, cause your gonna want to drive it when your all done.

Minus the smog delete pulley then.

Total is now $3950.00

should I upgrade my electical junk??
what about a torque arm?
will i need an afpr?
or bigger injectors?

My post must be invisible :sillylol:

My post must be invisible


HA HA AHA HA HA
after i saw
the 350 i didn't pay attention
ha ha ha ha ha ha !!!!!!

Thats to bad, cause there is no replacement for discplacement. You will know what that means when u dump all that money into that 305 and u max it out running 13's and a stock LS1 blows by you like you were nothing....then u will think differently about that special 305 of yours.

thanx but no thanx bird.....
I'm out just to make a donkey out of guys
like you. Don't hate on me cause I have
the balls to build a HOT 305 without
Nitrous (aka Car Steroids) and getting
better gas mileage to boot.

:lala: shake 'dem hata's off

Alright, well I will be looking forward to ur time slips then.

You have 4g to drop on it and you want to keep the L03? I don't get it. I like my engine, too... if you have a morbidly obese woman, she won't get much out of $4000 in a load of makeup, clothes, and hairstyling products; you're better off spending the $$ on the problem (liposuction, baby!). Don't nickle & dime the L03 and spend 10x the work on it, put in something bigger - it'll be more solid, last longer, and be less work for you. Then you can take the xtra $1-2000 and beef up the suspension, brakes, tires, etc.

If, for some reason (inferiority complex?) you can't part with the 305, put a blower on it! (with the full exhaust and new heads, cam, intake you mentioned).

not everyone wants the 350..... anybody can build a 350 and make it superfast!! Besides, if ya got a the baddest 350, if ya cant get it to the ground ur nothin. Some of us want the 305 because its "the underdog" and me personaly like to prove folks wrong!! Go ahead and build those 305's cause i got one comin too with a little superchargin to back up the lack of cubes. Even if some of the 350's can beat me......we'll just see who can run the farthest on a tank of gas!HAHA. Just make sure when you build em you put your own touch to em cause thats what this thing is all about.

AMEN TO THAT BROTHER!!!

i definately like eriks idea way better then build the LO3. you have 4,000. you guys talk about gas mileage have you thought about strenght, a built up engine is WAY stronger then your stock bottem end. its way easier to get more power out of a 350. but thats all i am going to say i shouldnt of even posted a post like this. do what ya want and show me the time slips.
ps look at the sig

funny......
brody u side w/ the 350 guys
and yet we plan on doing the same
exact mods.

By this logic, you should just drop in a V-6... No, better yet, how 'bout a 4? Drop in a VTEC or something and go FWD! Then you could really be the underdog!! :lala: :lala:

like I said earlier:


:lala: shake 'dem hata's off

Hell Yea... Build the LO3, why remove it if it runs so great! I was a the same point, I wanted to get a 350, but then I drove my car for the first time in a few months and decided to mod the LO3, it's a great engine!

hell yeah i side with them. its an easier way to go faster. IMO anybody thats says i want to go fast the hard way isnt thinking about all their options correctly. i am modding the LO3 for a couple of reasons:
1. its cheaper i dont have 4gs to spend on my car
2. its my daily driver i cant afford to have to car down for a week or more while a swap engines

so a brand new 350 wouldnt run great

cmon Joel...... i said underdog....not under the table!! Im not doggin 350's! I think there a great engine! Thing is...i like my 305 and thats whats been good to me. In my more stupid days of driving i ran that sucker way hot a bunch of times and now not so much as a hint of smoke or lost compression. Ive got a lot of repect for that motor because they can take alot. Besides....DIFFERENT is the key here....not STUPID!! Besides....its the only motor ive owned that hasnt shown me the rod while it was not being rebuilt.....gotta go now and find some wood to knock on!!

Build the Suspension and Rear End....
New heads
LT-1 cam or maybe Crane 2010 roller cam...
Put something like 3:42 or 3:73's (posi)
New Intake Manfold like the 300-49 or similar.
TBI spacer...
EGR valve
SLP (or similar) Headers, Hiflow Cat, 3" tubes to flowmaster 80
would make a nice driver...
Nothing too extravigant, but you can work from that point.
Keeping it pretty close to stock and giving it a tighter suspension and better rear end....
It would definitely wake up the car!
Then go from that point....

agreed.
I think I'll go with
some ported l98's and an lt4cam
dual hi-flo cats
posi and 3.73's
not sure about intakes tho

Ummm Dual exhaust is not a good plan... That could be a mess and you would lose torque.
Remember we are keeping the economy good on the car too.
just opening it up is good. Too much and you're losing energy.
Another thing you are doing when you go that route is expensive work. Most of the thridgens were designed with one tube going back from the Y pipe....
There will be insignificant difference between dual and single exhaust too. You already will be giving it air to breathe. You are giving it the air to exhaust....
If you want to have a street dominator.... NO it will not be a lightning fast car, but it will be solid and get up and go! It will be very impressive! You will love it!

I was told that I would need to
run dual cats to keep it smog legal
(Cali)

you only need dual cats if your car came with them from the factory

hey ride.....i found ya some 00 vette heads on ebay cast # 853. There biddin right now for em but he'll sell now for 275. Heres the link if you or anyone else is intersted...http://cgi.aol.ebay.com/ebaymotors/a...425128&r=0&t=0

Can't you answer that yourself, let me help....Probably!

I never said a 350 wouldn't run great, but I personally don't see the point in removing my perfectly fine engine. I'll have a good time seeing what I can make my 305 do. If it were to blow up, yea I would get a 350.

ls1 heads wont work

You only need a single hiflow cat right where the existing cat is. You will be fine. You don't need dual cats unless you are doing a true dual exhaust system.

oh.... my bad!

thanx v8powr 4 tryin' tho'
I wish those were the aluminum l98's
I think they were available in the
'vette from 86 to 91
thanx to everyone for the responses
tho'. Even u 305 haters.

why dont you want a power adder?

i'll feel like a ***** if I have nos or something
it's cheating IMHO a procharger would be nice
tho, but i would have to forge the bottom end

I'd forget the dual cats and just get a 3" cat.

I've thought long and hard about the 305/350 debate since I almost out of mods except the block itself.

As much as I think a well built 305 would make me proud, I KNOW I would be disappointed the first time I had my A$$ handed to me by a well built 350. Besides, what engines do MOST Camaro owners have in them?

I mean no disrespect to the 305 lovers.
So for anyone wanting to beef up the 305 because of financial or nostalgic reasons, go for it. But I'll bet a 6-pack that you are gonna feel the same way I would should what I mentioned happened to you.

You can build a 305 that can keep up with a 350. Yes it's true I read it on 3rd gen.org com it MUST be true.

I suggest you get some books on engines and start learning what you're talking about.

For THE SAME money you are willing to spend on the 305 you can build a 350 and make MORE power.

You're contradicting yourself.

Typical problem with 305 lovers. :sillylol:

Earlier you said one of your main concerns (and you tried to use it as a bragging point) was fuel milage, but then you want to put on a supercharger?

Well how much better can you get than using a 305 and building it to run about 250HP, then shooting an extra 100HP of NOS in there for drag runs, or a challange by a true '*****'? That's the main purpose of using nitrous in a street/strip car.

I guess the real question should be if you are so concerned with MPG, then why do you want a supercharger?

Look into a turbo instead. Same concept as nitrous. Power when you need/want it, but doesn't disrupt MPG when you're not using it.

AJ

so n2o is cheating

n2o would give you the extra power you want only when you need it and only affect your mpg when you use it....a supercharger is gonna be using more gas all the time and youll have more cyclinder pressure all the time compared the 10 seconds at a time the n2o will...n2o is also 1/4 the price or less of the cheapest of superchargers and im sure its much easier to install. id say go with n2o. i plan on keeping the 305 for the fact i cant afford a swap and im not looking for a drag car im looking for mild performance...i dont think it would be hard to break 12s with a 305 if its setup right...look what camaroracer1992 did...he ran a 13.1 with n2o stock cam, stock heads, stock TBI i mean with a modded tbi/or carb, new cam, heads, and ALOT of suspension mods which you gonna need either way you go you can get into the low 13's all motor probably. then id say high 12's with some juice...thatll outrun most lt1 and ls1s out there and alot of the mustangs to and no rice will touch you

If the engine runs....
Keeping it as close to stock is a good plan.
If this guy wants to take it to the strip and race it....
Nope.
I just think improving around the motor first would be good since it runs and the guy said he wanted to keep his engine.
Still would replace the cam with a nicer one.
Get the rear-end gears and the posi. (be sure to get the speedo adjusted to your new gears too....)
Get the intake and exhaust.
Get the suspension tight.
Nice daily driver.
It would pull and be very wicked.

There are things I need to do with my car, but unfortunately, my engine died and I had to get the engine first.
I did go 350. Regrets? NONE.
I want to do the suspension and especially the rear-end.
It's getting there a more and more....
http://www.lvfbody.com/whoismember.asp?memberID=101
Mods done so far are there....
Much much more to do!

I don't get this gas mileage thing.

1. My 91 Camaro 5.0 TBI A4 with 3.42 gears gets consistent 26 mpg.

2. My 99 Trans Am A4 with 3.23 gears gets consistent 26 mpg on the same trip and has twice the hp.

3. My 92 GMC truck with 5.7L TB1 and 3.42 gears and 1000 lbs extra weight and LT1 cam gets 19.5 mpg consistently on the same trip.


I doubt very seriously I could double my 305's horse power and get the same gas mileage as my LS1. A slightly milder 350 setup well tuned will yield as good a gas mileage and better reliablility than a 305 built hotter to keep up. The more hp you squeeze the less reliable it becomes. If you were to spend $1000 on beefing your 305 up to run close to LT1 power then that is ok. But to spend $4000 on a 305 (300+hp) with the illusion of better fuel economy and reliability will cause regrets down the line. I wish I had built a 350 comes to mind.

Who says the $4000 is going into the engine? The money is being used mostly for suspension and rear-end.... Some is used for the exhaust. Most of it will be used around the motor. An aluminum driveshaft is a good idea too.
The only engine work would be a cam replacement, a new intake manifold, and possibly new heads.
These are things that will be done either way.
My .02

Do you have a 5 speed? If you do, don't ignore it. A $4000 motor will eat that tranny alive.

Check out the 3rd column from the left....Thats a pretty good point right there.

trust me, comming from a guy who used to love the lo3.

you only want to keep it until you learn the truth. the strongest lo3 in the world hasnt made over 350 hp.

and then you buy a 350, and you realize, after you have a strong 350, you still have the choice to go back someday and build a nice 305. Has anybody who ever had a 350 went back and built a 305 for fun, just to see what it can do. NO because what it ends up doing, isnt fun. 13s

it would be dumb in my opinion to just throw 4000 into an engine without any other mods on the car, heres what i think you should do,
SLP Headers ~ 400
Hi flow cat ~ 100
3" intermediate ~100
SLP take off posi = 85 (on sale right now)
Richmond 3.42 or 3.73 gears + install ~ 500
Spohn SFCs = 155
Spohn adjustable LCAs = 145
Spohn relocation brackets = 65
PST or PSC front end and steering rebuild kit/parts ~400
Spohn adjustable panhard bar = 110
KYB or better struts and shocks = 160-500 (depending on what you want)
Eibach Pro Kit springs = 240
Edelbrock STB = 130
LO5 engine 1500
LT1 cam = 35

This would not complete the engine, but i think you should do everything up until you are ready for the engine, save up alittle bit more money, and build a nice 350. I pretty much laid out what i am going to be doing over the next few years. HOpe this helps

Once you build a 350 you want a 383 then a 406, then a 454 etc. etc.

although a 350 is 45 cubes, I still have a perfect v8.
Unlike most of you I don't have the space or equipment
for an engine swap. Even if I did swap for a 350,
I would wanna change the heads, cam, and intake
right away anyway. 2) Ya'll must've misunderstood me
I DON'T WANT A POWER ADDER!!!! This is gonna be a
n/a engine and
#3) My 305 is gonna make well over 300 hp
like you guys have mentioned. How??
By using the best possible parts in the best
tuned combination.
Why not make your motor the best it can be?
I see several 350 owners on this board not
making 300hp bc they're using cheap parts.

I say go for the juggular the first time around.
