That's a good question. I know they are Magnum based, and I think now ther is a pkg you can get to add an eccentric to the cam...But I dont know if the timing cover even has the flange now... Sorry I cant help with that one.
Not sure but they need to be pulled apart and checked regardless so it's easy enough to add one if it's not there. Mancini should have the kit to add it.
The next question is do they have provisions for the mounting of the fuel pump? If they don't then electric is the only answer.
"update"
Just looked in the performance book and they have the provisions so the cam will be the determining factor. They are based on the magnum engines but use early style water pump housing with the fuel pump mount.
