    Stroker Kit. There is no replacement for displacement, so punch out your 302 V8 to a more respectable 331 for more asphalt-chewing horsepower with a Scat Stroker Series 9000 Street-Strip Rotating Assembly.

    Kit Includes. Maximize the displacement of your engine with a cubic inch-enhancing stroker kit that includes a 9000 Series cast crankshaft, Pro Stock I-beam connecting rods with ARP 8740 3/8" cap screw bolts, forged flat top pistons as well as rings and main & rod bearings.

    Compression Ratio. The Scat Stroker Kit will allow for different compression ratios depending on the heads installed. Examples: 10.4:1 with 58cc heads; 9.7:1 with 64cc heads; 8.9:1 with 70cc heads.

    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 Series 9000 331ci Street-Strip 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.
