I have a 93 250 with a 7.5l and want to know what is needed to convert it to carb so i can possibly run like a 671 blower and get some more power. I already know where to get a standalone computer for the tranny im just not that engine savvy thanks

 

the efi heads and the carb'd heads are unforetunetly totally different. the carb manifolds will not fit onto the efi heads as the intake ports are totally different and the port mismatch will cause huge vacuum leaks.
you will have to change the heads and intake as a combo if you want to run a carb on your engine.

i am not aware of anyone making a carb manifold for the efi heads, but that is not to say there isn't one out there. maybe someone else knows of one being made. i am 100% sure no one makes a blower maniflod for the efi heads.

There is an adapter available to mount a carb on the EFI manifold. Do a search and you will find it. Costs about $100 and is much simpler than screwing around changing heads and intake.
