You didn't say who made it, but you should check the rulebook: "Stock OEM or NHRA-accepted aftermarket crankshaft mandatory. Aftermarket crank must retain OEM configuration (i.e., billets, knife edging, etc. prohibited). Lightening of crankshaft other than normal balance job prohibited. Aftermarket SFI Spec 18.1 harmonic balancer mandatory in AAA/S through G/S and AAA/SA through G/SA. See General Regulations 1:2. "
….and you can sort through the link below
Good Luck and Merry Christmas
