3970010 Block Q's
I have that block (actually my dads) and he wants to use for a 383 build up. When he took it apart it only had 2 Bolt mains . Just wondering if it can be changed to a 4 main without weeking the block? or will it be okay as just a 2 bolt block. Its going to be mainly built for towing, approx 400 hp 450 ft.lbs. torque.the Dart SR stock replacement Iron head.
