600 CFM, all I need. Check my math!

Nice link, thanks. Do you think the default 83% VE is about right? If so, makes me wonder if a 500 CFM would be even a smidge better...

Naaaaah. The P.O. said it had upgraded cams, he said it was 268's both intake and exhaust. No telling what else was done, it's not exactly stock. So I upgraded the VE to 88% (halfway between 83% and 92%) and considered that most V8's redline about 6,500 rpm. That put it at 595 cfm.

So a 600 should be the best application.

Next would be, dumping the 1407. No doubt, I'm going to dump it. Should I dump it before messing with it? Or should I save myself ~$350 and tune it as best it can be and see if I'm happy?
