The forged Pontiac crankshafts pictured here are the first ones we received and tested. The forged crankshaft pictured is the actual 4.25 inch stroke forging and was installed in the MR-1 block it is sitting next to for testing. The 505 cid engine made 850 hp and 716 ft lbs of torque. We have also sent material to independent labs / metallurgists for testing as well. These cranks are available if both 4.25 and 4.50" strokes, 3" main journals and BBC rod journals.
Our first 4.50" Pontiac forged crank was installed in our 540 cid Tin Indian Performance Rear Engine Dragster power plant. That engine made 950 hp and 763 ft lbs of torque with a set of KRE High Ports and a single 4 bbl carburetor. Car has gone a best of 7.50 @ 175 mph!
