Excuse my ignorance, but can someone help ID a GM 396/427 forged steel crank.
The casting number is either "7115" or "9115" the crank appears to have been cross-drilled from the factory. Thanks

Factory 427 crank is 7115.

Thanks Jason.

Were "7115" cranks used in passenger cars or trucks or both for that matter? I was under the impression that factory cross-drilled cranks were only used in hi-performance vehicles for better lubrication.
