Looking for the ultimate 6.4 based stroker kit for your max effort NA build? Look no further than the FRP 422 high compression stroker kit. Our kit is specially designed for high rpm durability. We also have a 426ci option that uses a 4.050 crank and 6.175 rod for even more displacement and compression!
Unlike most stroker kits that come with a 6.125 rod, our kit includes a 6.200 rod and 4.00 stroke which equates to a higher wrist pin location for maximum stability at higher rpms. The piston comes with a +7 dome that is stock Eagle(5.7L) and Apache(6.4L) chamber friendly. This allows end user to achieve compression ratios 13-15:1 depending on gasket and head choice.
Valve pockets have also been opened and deepened to accept valves up to 2.200" diameter and the largest camshafts we can manufacture. Spin this rotating assembly past 8000rpm with confidence!
All assemblies are 1300 horsepower capable.
