How do I know what size MAF I need?

Current combo:
306" 9.9:1, AFR165 RPM II intake, 24lb injectors, 70mm TB and EGR-and I have not gotten a camshaft yet. Probably something somewhat mild. Car is not running yet and I don't have anything but a stock MAF at the moment.

I want to measure mine. It doesn't look that tall.

That, or bigger. There really is no magic golden rule as far as sizing your MAF. You just want to size it big enough so that it is not a "choke point" in your system.

IMO : 75 or 80

Make sure you have it calibrated to match your 24# injectors.
