hey guys, i've got a 1978 firebird formula THAT CAME STOCK with a chevy 350 and saginaw four speed...weirdo combination, no?

anyway, i get flamed hardcore whenever i try to talk to firebird guys about my drivetrain, so i figured i might get a little more love out of you boys.

on to the actual point of the topic: can anybody tell me the stock compression ratio on a 78 350?

Pretty sure Sharpeye nailed it, he has a .....sharp eye.... http://www.nastyz28.com/ubb/wink.gif
You could probably get the correct info on that from the "info" or stats page at the beginning of this site, I would assume they would be the same.

Those Firebird guys are a little rough when you dont have a Poncho engine in your Firebird. Sometimes I dont get those guys! Just tell them your putting in a 4cyl Iron Duke in it (hey, its a Poncho engine right?).. J/K! Hang out here, skip those guys. We have a few regulars here that dont own a Camaro, we dont pick on them too bad. Heck, maybe we can convince you to put a Ford motor in that Bird then go piss off the Mustang guys & the Bird gang!!

11.74/118mph, thats all..

lol atleast you own a 2nd gen iv got a thirdgen trans am but hell its got a chevy 350 in it "id prefer a poncho 455" but not being picky lol this is a great place to hang out even if you had a ford with engine problems or a poncho engine problem there are people here that are willing to help out

Actually, didn't alot of the later 2G Firebirds come with Chevy motors?

ALL Canadian built Pontiac trans ams and firebirds came with chevy engines.

I know a guy in town that has a 69 Firebird Trans Am that came from canada, and guess what? It has a Chevy 302 in it with the cross ram induction and a muncie M22 4spd.
I think it is worth quite a bit of money.

i would think so http://www.nastyz28.com/ubb/redface.gif

yeah i don't really understand why they give me crap. they swear to me that the car would be worth more if i pulled that motor and dropped a 455 in than if i left it numbers matching, all original.

it's ok though...me and my old friend mr. motown block will show them what 450+ cubic inches are supposed to perform like in a few years... http://www.nastyz28.com/ubb/biggrin.gif

I have a 74 Firebird formula that came with a 350 and factory 3 speed on the floor...how rare is that?

Not rare at all, you have a pontiac engine, Formula has a pontiac that came with a chevy 350 from the factory.

My 78 Phoenix came with 305 Chevy, quite common after 1975.

the engine is a pontiac...but i was wondering about the 3 speed combo. parting it out anyway, so no matter.
