308 cu.in horse power

[glenn95gt]

what is wrong with your block? How many miles, is it burning oil, have you done a compression test? That 308 won't make that much more HP than your 302. The only thing it has going for it is it has forged pistons. Best thing to do is just rebuild your 302 with forged internals. Get a better set of heads, and maybe a custom grind cam. Remember that 308 is bored .040 over, meaning it is almost at the end of it's life if you were to blow your motor.
