I have an 87 Trans Am it has a 305 TPI, 3.23 gears, 4 speed auto, engine rebuild with new cam, 3" flowmaster cat back, WS6 suspension package, 1 1/2" drop springs, new sway bar bushings, ball joints, struts, shocks, sway bars, rotors, calipers and brakes and that's about it as far as mods go.
My friend has an 89 IROC with a new 350 crate engine, tuned port injected ofcoarse, with new heads, headers, gutted cat, 3" exhaust, and four wheel discs. My cousin was riding with him and he said that the car doesn't feel that fast, so I'm gonna race him. What are your thoughts on the race? Will I beat him? What do I need to beat him? Anything.
Thanx

 

you have basically the same car i do and you can see my mods in my sig. i have beaten an 89 GTA and an 89 IROC, both had 350s. you will need to hook up, and get as much of a jump off the line as you can. cuz he'll get ya if ya don't. good luck

STILL Looking For:
An 87 IROC-Z28 350 TPI

 

What kind of crate engine does he have, there are some that are stock rated at 250 hp like mine and then there are ZZ4s that have like 330hp, I would most likely say he will win, but there are many other circumstances that come into play. Like you said someone road with him and said it didn't seem that quick. Maybe through installing the new engine something got out of whack. How does the IROC run as in condition wise. What gears does it have? I wouldn't even think he would need gears to beat you.

I didn't see you mention that you have headers, if this is the case you will definately lose and will need them, because you can't take full effect of your cam and 3" exhaust with out headers.

 

Last weekend I raced an 89 Firebird Formula 305 w/ 3.73 gears with quite a few mods. I couldnt believe how strong I pulled on him (beat him by over 3 car lenghts)with only a set of 2.77s out back. Needless to say -the 350 has a huge advantage over the 305. ...I have noticed that people only lie about gears in the other direction -i.e. /the Mustang guy that just beat you with slicks and 4.10 gears that says "Man, I swear it only has 2.73 gears!".

I'm pretty sure he has 2.73 gears, he has rear discs but I'm positive it's not posi. I don't know what came stock in the IROC, but the gearing is all stock. His engine is a regular crate engine, not rated over 250hp. I believe it came from carquest, not sure. I've got my money on me. I'll let you know the outcome.

 

he will work you badly. even if he has the lower crate engine, the amount of torque all crates have is far superior than a 305. we are talking massive mods to beat a 350. later

 

so is my 85 Ta with a carbed 305 a freak of nature, or can i just build a motor?

oh yeah the whole car cost me around $800 to put togeather including the body!

 

his engine mods:
new cam, 3" flowmaster cat back
your mods:
58cc 305 truck heads
shorty headers
holley 3310
edelbrock per rpm
big old comp cam
a 100 shot of nitrous
and a 92 t-5

i wonder tard, he has tpi, you are carbed, you have a 100 shot of nos, a 5 speed, and racing tires. you dont know how to build an engine but you sure know how to destroy a drivetrain/engine.

 

first off nothing is modified, but the exhaust, a cam is not a "MOD" i didn't modify the cam by having it reground, i changed it. the headers are bolted on, i did "mod" the dip stick to work with the headers, AND I DON"T RUN NOS, i use NITROUS EXPRESS,
as for killing the motor, i know a little more than the avrage joe about what i'm doing. this is my daily driver, it runs a best time 10 flat in the 1/8 on the motor and get good good gas milage, and i run a 8.2 on the nitrous, go look a 1/4 to 1/8 convesion chart and see what kinda times thats taking off with a mild 100 shot, i have friends around here that have bigger shots on hondas, learn about nitrous before you talk smack,

 

oh any one else got a 305 running 12's? i know there is some guys in arizona, anyone else?

 

lol i wasnt gonna be a **** but since you were i will point some things out that are gonna break on you in the near future:

a 100 shot of nitrous - no matter what everyone says it is still harmful to a motor.

putting that much horsepower through a t-5- these things break real quick under stress.

3.08 9 bolt + et drags = broken differential

he wanted to know if a near stock 305 can beat a 350, you answered with an anything but stock 305 on NOS. it makes perfect sense the times you run, while it does run-
and btw, a mod is anything you do to MODify your car, i almost feel sorry enough for you not to argue with you...

 

Go ahead and race him,I think you have a chance.And as far as the guy with the 305 that runs 12s I take my hat off to you and anybody else that has these motors running that fast or faster!

ok well besides a tranny mount and a torque arm bushing i have not broke any thing in two years or racing it! and also i ran a combo close to this with a 327 with a turbo 350, i'm sorry but if you shift like your trying to break it you will, i'm not trying to be an *** , also i think if the guy with the 305 looks in to a good combo he will really put a spank on the old 350, i love eating up ls1's. i have a combo that cost nothing to build and the fact is if i blow the motor and our shop i have 3 305's just sitting there! i also have the 3.23 7 5/8 10 bolt thats out of my 85 camaro, as for the t-5 i have the tubro 350 sitting there with a 2600 stall, i'm using the t-5 because it has more gear in first. i'm just thinking that a sunk top hasn't been rebuilt 305 can make the kinda power to move these cars, and you are so wrong about the nitrous! go call john stuart, at nitrous werehouse how helped me get over alot of my fears of nitrous, he is the guy who started ICE nitrous systems and Nitrous Express, he's a nice guy and and will answer all e-mails

 

my money is on the 305. ALL you 350 guys can pack it in your shorts cause if your cars were half as fast as you thought they were you would really have somethin. i trounced 2 350 cars both were in nice shape, and i don't even have my 373s in yet. and if u don't believe me, come on out and see how a good tight 305 runs, you will be suprised.

Flame red shut the PHUC UP.... you have 190 HP (i kinda think the 86 305 TPI auto has like 170, but not sure) a 350 TPI has 230 HP.................... DO YOU GET THE PICTURE lets add torque to
YOU:
190 HP
290 TQ
THEM:
230 HP
340 TQ
You will get pounded like a ***get!

 

i think it will be close and who ever got the better parts such as heads, etc will win

 

well import i have modded mine and headers make a big difference. i don't care if u don't believe me, but if u wanna find out for yourself come on over here and we'll go. here is a list of my kills;

i don't know my 1/4 mile time but i can get 0-60 in about 6.4

 

you spelled fa ggot wrong

 

wow, thanks for all the opinionation. I'll be sure and video tape this one so everyone can see. I think that it would be kinda funny to beat him, not that I like racing other thirdgens, but it might show everyone that a 305 can take a 350 if u know what ur doing and don't talk a lot of crap that u can't back up.

 

FlameRed, your car is probably running low 15's or very high 14's. Most 350 3rd gens. will run 14's. So it's not likely that you have a faster car than them, just maybe you're a better driver than them. I don't car what you say a modded 305 will not be able to beat a modded 350. It just can't be done, unless the mods on the 305 severly outweigh the 350's.

0-60 ??? What does it run in the 1/4?

Check my sig out -there's my 1/4 time / where's your's? /0-60 in 6.4? --that's like a 14.9 if that. Those so called kills must have been asleep. -or they put down a football field length of rubber before they got traction. --Mod for mod, a 305 will never outrun a 350 ... period! / Sometime in the future when you do get a 350, you will finally understand.

Well heres a funny story about the 350-305 debate.I bought an L98 out of a formula and sold my 305 to a friend with an 86 IROC.My Iroc was a 5 speed so the 305 was factory rated at 220 hp.After both motors were put in i asked him to race me.He had an auto and me a manual.He handed me my *** twice.As you could imagine i was quite pissed after spending thousands to go slower but i was really bad at drive=ing a manual.ALso what helped him was less torque than my 350.While i spun and spun and spun he hooked and left me.By the end of the race i would be catching him just wasnt enough.So it is very possible.

 

I think you have a good chance as long as its not a zz4 crate motor,if its a oe crate motor then it might be a good race,i think he might get you as most crate motors are 250hp+,i know all 305 tpis ranged from 190hp to 230 hp i believe through 85-92 depending on if it was 5 speed or not,i have beaten 350 cars with my 305 but they were stock 350s and mine has mods that compensated the hp difference i would believe,plus my reaction time is pretty good and who gets the jump off the line can make or break you in a race,shift her a 4500-4700 rpms as the car has the most power there, good luck.

350TPI, of course you lost, you know how much time you lose by spinning tires. You didn't pay all that money to lose, you just got to learn how to feather the throttle and not spin.

I'm not gonna say my car is fast, it runs a 15.0 at the track, But I did beat my friend in his 89 formula 350/auto. I raced him three times, every race was pretty much the same...No spinning off the line, his car shifted into 2nd before mine (with tires chirping on his end) and he never made up the ground I made by my car shifting at the higher redline. There are slower 350 cars out there...not every 350 car runs mid 14's. BUT the majority of them will kick our (305 guys) @ss.
