: I have a 91 z28 , currently running a paxton w/8psi
: can I swap in a zz4 motor and use my tpi on the zz4,
: and what is the cr ratio for the zz4.
Re:Your intake will have to modified to change the angle on the two center bolts.Don't forget there is no heat crossover on the heads. your EGR valve will not function.The compression ratio is 10:1.You need to check with Paxton on blower compatibility.
