Best 273 and 318 builds (NO 360's please)

Why the overtorqued head bolts? All that does is stretch them and distort the block.

The 268S cam is a great choice, but small port heads perform better with single plane intakes. Think stock 273 4bbl, marine manifolds, Holley street dominators, Edelbrock streetmasters, or a real find, the torker 318.

IMO at least, I just have gone dual plane to single plane so many times, and said WOW!
