65 dart small block

A .513" lift cam? Any particular reasoning behind this particular number? There's no real reason to go past about .480 with a stock 360 head, unless you want to replace the entire valvetrain. Keep it simple and use something like a Comp XE268. Save your money for headers if you plan to run them, you'll spend plenty on an early A-Body. Cheap, big cams, and stock compression usually don't add up to screaming performance.

Then there's a new transmission with a GOOD converter, a new rear axle... the list goes on.
