Kit Includes. Maximize the displacement of your engine with a cubic inch-enhancing stroker kit that includes a 4340 forged crankshaft, 4340 forged H-beam connecting rods with ARP 8740 7/16" cap screw bolts, premium forged flat top pistons as well as rings and main & rod bearings.

Unbalanced Kit. This Rotating Assembly comes unbalanced and will need to be professionally balanced before installation. It requires the use of a 28 oz harmonic balancer as well as a matching 28 oz flywheel or flexplate.

Application. This Scat Stroker 4340 Forged Competition 331ci Rotating Assembly Kit is designed to fit 1979 to 1995 Mustangs equipped with the iconic pushrod 5.0L engine including the 5.0 LX, GT and SVT Cobra models.

  • You will gain more HP. But what kind of Heads and Other performance parts are you going to add? To get more POWER you need to add a lot of extras. Can't really tell the HP without knowing what other parts you are running. Call AmericanMuscle Tech maybe they can tell you.
