Are the Corvette TPI runners the same as the Camaro/Firebird runners? - Third Generation F-Body Message Boards

CamaroX84 · 03-27-2001, 09:05 PM

Does anybody know if the Corvette TPI intake runners are larger than those of the f-bodies? Also, what is different between a Vette 5.7 TPI and a Camaro/Firebird 5.7 TPI besides the aluminum heads? Thanks.

The runners are the same (they are smoother looking than camaro runners) but the base is different. The base has no egr provisions.

No, the base does have EGR, but its plumbed in from the exhaust to the back of the intake instead of thru the heads like on the f-body.

so now when someone tells me that they swapped in a corvette TPI motor i can tell them they are full of crap unless i see the EGR plumbed this way
