budget build 360

A slick trick, now that I think about it, is/was the W2 head with the 55 cc chamber. On a low comp mill like yours, you can get about a 9.-1 with that head, or so, actually, depends on how deep the slugs are.

Then you could mill the head from there. MoPar used to sell that head in an assembly. Not anymore now. Just the Commando I think, but for surely the Super Commando. (Still can not find any info on it.)

IDK what kind of milling an Edelbrock can take. Or the ones Stroker posted. Just a thought, another possible route.
