Going back to Indy, I have heard of guys running their "bracket" motor. I guess since some have run these in NHRA class runs they are leagal SS hemis and compression ratio is the same. What is the difference in these and an all out class runner? I assume cam size, lighting of parts, crank, rods, pistons is done. What else???
