  Pontiac Forged Crankshafts

Here are the new 4340 non-twist forged Pontiac crankshafts from Ohio Crank. We've checked these forged cranks out and they are very good quality. More fine products from the great state of Ohio. We've done quite extensive testing on the dyno and track with these cranks. We recommend these for applications that are for 600-1400 HP.   Of course you can use these on lower horsepower engine if you want too.
