    Title says it all..I have a trashed BBC starter the came on my BBC and a good SBC starter in my truck now...Will the SBC starter work on the BBC as long as the flywheel is the same size and the bolt pattern is the same on the starter?

    Thx

    Nope, no real physical differences. As long as they are both for the same size flywheel, they are interchangeable. In fact, I looked up the starter for a 1970 LS7 454 Corvette for my SB 388 stroker. I figured a starter made for a 12:1 BB will crank over my 9.5:1 SB. /forums/images/graemlins/thumb.gif

    Great, that's what I thought from comparing numbers, but it's always nice to get some confirmation.

    The only difference in them is high torque vs. the standard torque. High torque uses the copper spacer on the commutator brush tab due to a longer armature and longer magnets.
