Honestly, I wouldn't get hung up on having EFI..just build a nice carb motor and enjoy it...spend the extra cash on a decent set of headers...if you really have your heart set on EFI, I would use the 500efi intake...

I saw a few folks selling 500 efi's wasn't sure if they would work without needing to do more motor work. I'm assuming a nice intake carb setup will get me close to fuel economy and HP of MPI.

Yeah, that I don't know...not an engine expert at all, but if I was gonna build a efi 502 motor I would build a 500 clone...if it were me, I would use the money I was gonna spend on the efi system to build a healthy carb motor for sure...

A 454 mag mpi and 502 mag mpi of same vintage have the same intake manifolds, the 454 efi 310 hp has all junk parts, oval port intake, cast crank, cast pistons, etc, Smitty

Ended up going with a carp setup for now.

I think its a good choice. Not to mention my efi setup was heavy!!! Think it weighed over 90 lbs when I shipped it out.
