I need some advice on MPFI for my 302. Edelbrock has what looks like a nice Pro-Flo MPFI conversion for $2500, complete kit. Holley has the Commander 950 MPFI system for about $3500 which I believe is a speed/density system like the Edelbrock. Then there is the good old Ford EEC IV computer and mass air sensor sytem. The mass-air sytem is supposed to be better for performance upgrades, anybody have any opinions or experiences with any of these sytems. I talked to a tech at Edelbrock who said superchargers are easily added to their system. He even recommended a few, so i don't know which is the best choice, I am thinking the Edelbrock.
