Here are the specs:

99% stock 74 Formula 400: 225hp, TH-400/3.08s. Heavy car--has a/c, pw, pdl. About 3800lbs

100% stock 88 IROC with the 170hp 305 TBI/700r4/2.73--most options, hardtop car. 3350lbs

Who do you think would win? what times?

 

My money is on you're Formula. Regardless of the huge weight difference, you're Poncho has a tremendous torque advantage (which you forgot to post)...

 

it will be a close one so I wouldn't count the LO3 out all together. Those birds were terribly slow.

 

Cut out the catalytic converter if you have one and bolt in a straight pipe. Buy an Edelbrock intake and Holley 750 cfm carb. Don't forget to post the results from the race.

 

no cat on pre 75s.

a big yes on headers, duals, intake, and maybe the carb. i personally had a lot of luck with the quad.

i had a 75 TA with 400 and 4 spd and it was pretty sad til i put the headers, duals, and dominator intake. re-curved the distributor and juiced up the carb some. she was sweet then. cracked 140 with it.

a little goes a looong way with a 400 cube engine.

 

Absolutely. I raced a two ton Pontiac Lemans last year, running a healthy 400 (open element, exhaust, Ram Air IV cam, excellent tune), and the car made a low 13 second 1/4 mile pass, without breaking a sweat...

 

15.8 for the Firebird and 16.2 for the Camaro.

Oddly enough the Camaro is faster off the line but acceleration falls off after the 1/8 mile. Thats where the Pontiac pulls ahead.

Guess the 3.06 first gear and the lighter weight do that. Not much low end in the Pontiac.

 

well its easy to open those pontic 400 up to some high numbers .unlike the l03 witch is a waste of money to modd.with under $1600 the 400 could be running with stock ls1s

 

Give that poncho some ram air heads, a healthy cam and longtubes. Then so smack around some ls1s.

 

how would you know all you have is a 2.8 and a l98 ???

have you ever seen a 400???

what kind of a stupid name is slinkoguy.i bet your some nerd working at a game store .why dont you go play some worlds of warcraft and leave us alone.

 

4bbl q-jet and an edlebrock air gap intake with full exhaust and that bird will be reborn

 

I agree GodSpeedGTA, but I also dont think the bird will have anyproblem at all killing an l03. Bird wins hands down, Iroc has no chance.
