The reciprocating assembly for this engine is available at Trans Am Racing (1531S-460, $1,850). this cast-steel crankshaft is manufactured by Scat and has a long 4.50-inch stroke. The cast-steel construction is a big step up from a gray-iron casting and is also less expensive than a forged-steel piece. Balancing the whole setup will run you $155 and is good insurance.
