I'm rounding up the pieces to rebuild my 1967 396. I'd like it to have a nicer sound and more power than stock. But it is for the street, not the strip.
I have the correct 1967 350 hp heads and 585 cfm holley. It likely will have a moderate street cam, forged TRW pistons (9.5 or 10 to 1 compression), and roller tip rockers that fit under stock valve covers. Although it will be balanced, I don't expect it will see high RPMs.
So far I haven't bought an intake manifold or exhaust manifolds. One option is to look for the correct intake manifold, not easy to find with the right date. Another possibility is to use an Edelbrock Performer intake. I'm wondering how many more horsepower the Edelbrock will give compared to the stock unit.
Similarly, I'm debating about whether to look for the correct exhaust manifolds or go with headers. Again, how much of a performance difference would I notice?
Thanks for the benefit of your experience.
