I'm glad you touched on rod length....it's a great tuning tool. The best combo's I've build or seen had EVERY component working in the same rpm range. That is why alot of times I suggest to guys who get their heads ported, that they change the cam. Porting changes rpm range as much as it changes power.

A few times a year, I email back and forth with Larry Meaux in Louisiana and he has really helped me to understand some of the things I find. He's also helped me to realize what you just said Jeff about every little detail affecting power.
I see you have a nice write up in Engine Masters magazine about your BB edelbrock heads!!
