I had a engine builder tell me a cast GM crank was better than forged GM on a circle track car. He said the forged crank is twisted to break the mold or somthing? Is there any truth to this?

cast gm will flex

oem gm is junk, and will crack all the time.

I used cast gm and scat, and several friends with close to the same combo used gm steel, they cracked a total of 5 in 20 races, they had a machine shop sponsor so didnt care I guess.

some guys will get on here and say their gm steel is seasons old and great, they are lucky I guess, I wouldnt use one for free.
