Give it some big compression, and a big cam. The rest is in the heads. (nothing else is left) LOL

And he did it with stock 273 heads (ported, I know...). Impressive! I would think the bigger bore of the 318 and better heads may get the 42 more hp needed for 500 hp @ 6500 rpms..... Just food for thought
