This SCAT crankshaft is designed specifically for SCCA Formula Ford (legal per FCS 9.1.1.B.12.k). It is as close to SCCA minimum weight (24 pounds 8 ounces) as possible while still allowing grinding of journals without going underweight.
This crankshaft is built specifically for SCCA-legal Formula Ford 1600 engines. A properly built, lightened, and balanced FF1600 engine should observe a redline of 6800 RPM. We do not recommened exceeding this RPM limit. This crankshaft has not been designed, tested, or approved for use in GT-spec engines.
Note: This "drop-in" version does not require any modification to your engine block. The counterweights on this version have been ground slightly to clear the stock main bearing webs in the block. This leaves less material for balancing. Extreme care and accuracy is required when balancing this crankshaft for competition use.
