I would like to know if you can use the FORD MAS EFI system on a Chevy. I currently have a speed density PowerJection 3 system that dosent like the the 6-8in of vac. I have a Chevy 421 ( sbc bored out ) w/ 520/540 236/242@.050 cam. It dyno'ed 625hm 600tq w/ a shop holley 750cfm carb.
I have never been able to get anywhere near 600hp with the PowerJection 3 .. more like 500hp at best and leaned out soo bad I clipped the rev limit to 5000rpm!

I want to use the cheap parts that ford has and maybe a up-graded MAS meter.

I have looked at MAS AIR FLO efi from ProMracing and its $4,000.00+ price tag scared me off.

I want to do this on cheap side..2000.00 or less..

Again I do not want a Speed Denisity unit,, I need the MAS air flow to work with my cam/engine combo

THANKS IN ADVANCE!!!
