<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: SuperNovaSS</div><div class="ubbcode-body">7115 is forged piston 427. That said, I've pulled apart many standard bore high perf 427s to find 6223 cranks that have likely been in place since new. In reality, if you are balancing the rotating assembly anyway the 7115 crank is just bragging rights/correctness.

You cant balance a 6223 for 427 application without expensive mallory.

Not true a 6223 will balance without mallory in a 427 , the only 6223 I have seen that had to have mallory was previously balanced for aluminum rods , I've built 3 in the last year using the nos 6223 on ebay , 2 had to have counterweights cut for piston clearance , not uncommon with factory style pistons

The 427 +.030 that I was running with cast pistons had no evidence of mallory -- balanced out OK ... TAZ
