Question on 302 c.i. engines


e5 e6 e7 all high out put small block heads

E5 & E7's are basically the same head. However the E6SE in no way can be called a "high output head" Not even considering the fact it was used on the 86 Stang HO motor. Replace a set of E5's or E7's with the E6 and the horsepower drops by 25 horses.
 
any 302 is carbed if you put it on it. no difference at all in the longblock, other than the old heads are crap. E7 or better. hell E7's aint really that great
