The reason I am asking is because I have one in my 572 that's in my dragster.

I just wanted to know if I should pull this motor apart and change the crank. It only has 94 passes and seems like alot of work, but thought I'd ask the experts.

Depending on power level and number of passes, a disassembly and inspection of everything, including magnaflux of the crank is recommended every couple years. A good magnaflux will see the start of the crack before it grows and breaks.
