65 barracuda engine swap

I took the 318 short block and put all my spun rod 273/4's parts on and into it and it kicked more ***. 1/8" walled convertor bushing is required, it's available here from 2 members. You know that 'ol small register 273 forged crank will fit into that 318....IDK if it even needs to be rebalanced as the 273-2 pistons used some very heavy pins to make up the weight of the taller 273/4 pistons and their lighter weight pins. 318 piston+ rod assembly and the 273-2 piston+rod assembly was nearly the same weight.

273 piston connecting rod and wrist pin....1576g
318 piston connecting rod and wrist pin....1572g
