Stroker Cranks

The Scat 4340 crankshaft is fully counterweighted to ensure a smoother running, better balanced engine. And each crank is brand new and made in one piece. Available with type 1 or type 4 main journals and with Porsche 912 or Chevy 2 inch rod journal, the 4340 crank comes standard or in a lightweight version, with a dowel pin or with a flange for rear hookup. Eight hardened dowel pins included.

If you’re looking for superior performance and reliability, the Moldex steel billet chromoly crank is for you. We feel that the Moldex crank is the strongest crank on the market today. It’s available in 82mm-90mm stroke, dowel or flanged.

Auto-Craft Stud Kit
8 MM/10 MM
High tensile ground finish chromoly steel head studs are a must when using higher compressions, exotic fuels and prolonged hard running. Standard factory studs will not tolerate the excessive strain of racing and will break – leaving you out of money! The extra thread length on the cylinder end will accommodate longer or shorter cylinders. Comes complete with 16 studs, 16 nuts and 16 washers.
10 x 12 MM 
This 10x12mm stud kit has a full radius blend to eliminate stress in threaded areas and broken studs. Pulling these studs out of the case is difficult because of the extra threaded area. These chromoly steel studs can be used in stock cases after the removal of standard factory inserts. The extra thread length on the cylinder end will accommodate longer or shorter cylinders. Comes complete with 16 studs, 16 nuts and 16 washers.

Fan Assembly

The answer to excessive cylinder head temperature, this lightweight fan assembly lowers cylinder head temperatures approximately 100 degrees, a must for the serious racer. We have tested this unit on both track and dyno, and feel that it deserves our endorsement. If you cannot run a water-cooled engine without a water pump, how can you run an air-cooled engine without an air pump?
