GM cast 350 crank question

I have a late model 1 pc. block and the 1 pc. seal cast crank. This is 350 stuf FYI.....Is this crank the same material etc., as the older #442 cranks? We have abused those older cast cranks in drag strip applications and I was just curious if the newer 1 pc. stuff would hold up at all...? Engines are only about 500 HP max....we do turn em about 7400 RPM though.........thoughts?

you'll be fine.
they will take more then people think,i'm not affraid of spinning a cast rod and crank assembly 7500 rpm's.done it for many years never once had a rod or crank just have to balance the rotating assembly put in arp rod bolts,do a little chamfering on the crank.good to go we ran this in a super late dirt i've seen people try this and windowed there block because they were to cheap or lazy to polish the rod beams.if you are running stock rods you must get rid of the casting line without doing any more then needed to clean it up and make it smooth.

I agree, a cast crank in a SBC is not a source of worry. Some people strive to have a steel crank, good if you can find one, but not needed at all in a street engine.
