You're gonna ruin that motor by carbin instead of fixing the EFI. You will lose 8-10 mpg and lose power to boot. Yes it is easier to build a carbed motor but the EFI is alot more capable than you think. IT also has a fuel management system that increases the MPG. Consider this, a Stock EFI 351 is 210hp and 325tq. A stock 2bbl carb 351 is 140hp and 250tq.

i understand that stock to stock the efi is alot better but im not building a stock motor if i was i would just rebuild and be done with it. by the time i do the work and get the chip burned what do i have a a lot of expense and a engine compartment that looks like hell. im going for a clean show look and i dont want a buch of wires and plumping and such. i guess ishould have been more clear in my intentions. sorry.

All I can tell you is it's a 94 comercial (truck) block.

When you get it running let us know how the change over went. This is still an option for me. Even if I would rather keep it EFI or not. But I have thought of doing this.
