I have recently bought a late model that came turnkey . I was wondering what the realistic hp on the motor could be . It a all aluminum 421 with good internals rhs heads full roller 3 stage drysump system on alky ! I was just kinda wondering what kinda numbers it could put out being a 23 degree motor with RHS heads !
