The bottom line is that unless you're building an all-out race engine that's going to be worn out or blown up in less than 1K miles, a well-built 302 will smoke both of them with the right gear ratio.

Very true. Looking for bang for buck. Hard to put a motor together with all bells and whistles for less than what some of these large assemblers are doing it for. For example: To buy a sniper FI system is 1500. Add it to an engine build and its 1K. Buy a serpentine belt system for a engine and your at 1500 once you get all pulleys etc. Add it onto an engine build and its 800. The list goes on and on.
