We've seen the emblems, the patinas, and the people of the Billetproof Nor-Cal show last weekend, and now it's time to look at some engines. Many, many small-block Chevy and Ford flatheads were present, of course, but we (Casadelshawn and I) made an effort to capture some of the less commonplace powerplants as well. Lots of photos here, so jump to see them all.
