I think it was in McCarthys book where he said he has seen less Pontiac cranks fail than he could count on one hand. Something like that.
I beat on my 30-30 455 crank for 30 years.
When I put a 4" crank into my 455 block it will be a PMD 428 crank. Steel crank will get me no advantage other than lightening my wallet.
