Title pretty much says it all:

Looking to build a healthy street/strip small block to power an E-body, backed up with a 4 or 5 speed manual trans.

Clearly, the budget will require some swap-meet/Craigslist shopping, but I'm not in a rush.

Aside from a 340/360 base for the cubes - what would you suggest? (assume that the core motor has already been purchased)
