with a pretty healthy cam of 246int/254ext and .495/.510 lift
2.5 exhaust
4.56 gears th350

im hoping for mid 13s and want some opinions

I think we know nothing about the Firebird... a '73 455 Super Duty..?
A '68 or '69 400..? Some Firebirds are monsters, and others are re-badged Camaros. One of the quickest street cars I've been in was a built '73 Super Duty... An 11 second street car in the late '70s, when a friend had it.

oh sorry, its a 1977 firebird with an olds engine and 2.73 gears

tire height for me is 26 inches

If he's got the stock 403, it's only around 8:1 compression, and made something like 190 HP... You'd tear him up.

If he's massaged it some, he may run OK...but with 2.73 gears, I'd say he still hasn't got a chance.

76z28 · 05-11-2010, 10:24 PM

yea, im trying to make him get some 3.42s at least or maybe 3.73 but he wont do it

sounds like a really nice strong sounding combo you got there. what kind of intake and carb you running?

your friends car sounds like its pretty slow unfortunately. hope he isnt dissapointed easily because it sounds like youre gonna be much faster than him.

i prefer double pumper/holley style carbs but even so, sounds like you should be in the mid 400's for hp at the flywheel. I bet that car really moves! whats it weigh? >3500lbs? I think you should be in the 12's without much problem!

THE EVIL TW1N · 05-12-2010, 07:58 PM

4.56 is A LOT of gear but perfect for the quarter mile. Im guessing you cant go faster than 110mph with those gears and tires though (6500rpm). That should be just enough for you though and probably at redline at the end of the quarter mile!

the 403 is a dog by today's standards.
