awesome boats for sure but i believe they handle better with small blocks. i think that is the same hull as the sport magnum and they don't have the freeboard or the beam to handle the heavier big blocks. nice boat for running the great lakes . . . .oh . . . forgot your not on the great lakes .
one other thing about that boat. if it has been converted to brovos there may be a weight trade off from the TRS drive and transmission to offset the heavier motors.
