edelbrock heads on a 318

Whoops, should've explained that more thoroughly...

It may be a cheaper option to go with a set of ported closed-chamber #302 heads from a late-80's truck/van 318. Although they wouldn't flow as much as the Eddies, they would still be a big improvement from your stock open-chamber heads. In fact, I have a pair in my garage just waiting for a cleanup (no porting, too much work for me now and not really worth it unless I go all-out) to go on my '70 318 along with a Performer intake, Lunati 262/268 cam, and iron 360 manifolds. Still not as much compression as I'd like (hoping for at least 9:1), but the high-velocity swirl-type ports and fast-ramp cam should help that out too.
