I have an '82 Z28 I've had since 1985 I'm about to start completely restoring so I can drive it every now and then. I've gotten bored with the current engine - 350 with B&M blower, TRW 8.4:1 blower pistons, DartII heads, Holly Projection 4, PJ gear drive, Edelbrock header system, all the typical goodies. I think I'm going to put twin turbos on it so I can ditch the cowl induction hood. It was cool in high school, but that was a long time ago.

Two questions:
1. Is there any difference between the 5.0L and 5.7L TPI intakes? (I'm going with aftermarket controls, so electronics don't matter)
2. How much air can be shoved through one? Will it be good enough for, say 700HP or should I stick with a standard manifold and throttle body?

 

The only diffrence is the injectors 19lb 305 22 lb 350 but if your going to have that much power you will probley need 36lb any whay other then that the chip is programed a little difrent nothing major. As far as how much air they make a 1000 cfm TB as far as Llong runner set up with 700 horses check out the power adder bored im sure you will find a few. Guido hope I didnt busher his name is working on one know that is probley going to put that out also try Andrie Skuliet I know he has a twin turbo car that is pritty mean.
