I am doing a 5.7 swap into my 85 Nissan 300zx and don't have much experience with Chevy v8's. I would really like to do a tpi setup and I have the opportunity to go pick up a stock vortek 350 out of a 90's suburban that has the tpi bolted onto it but its never been ran. My question is are the vortek heads and everything else going to be compatible with the tpi? I have a set of 194 heads from a different motor are they any better? What would you do?

 

If it is just centerbolt truck heads from 87-95, they are junk and are not vortec. Vortec is 96-98 truck and carried over in the vans for a few more years. They make a intake from scoffing dicky that works.

 

How do you identify vortek heads from others?

 

They have 4 intake bolt holes for one, for the other, you can look up casting numbers in the sticky above.

 

They also have very unique casting marks on the front of the heads. The intake bolts aren't at a 90deg angle to the intake mating surface also. They go straight down when the heads are on the engine.
