Stroker Kits - Done Right

VPE Vindicator Engine Kits are available in various displacements and are suitable for stock or aftermarket blocks, consisting of 4340 Steel H-Beam Connecting Rods, a 4340 Forged Steel Crankshaft and Probe PRS Series 2618-t61 Forged Pistons which feature Nitride Steel Top/Napier Second Ring Sets. They are perfectly suited for naturally aspirated high horsepower applications, or they can be set up with boost or increased compression for high performance street or street and strip combinations.

The longest rod feasible is utilized in each instance, which gains the maximum piston to counterweight and rod bolt to camshaft clearance possible, as well as decreased piston weight.

Altered stroke and/or compression ratios are not legal for use in emissions controlled vehicles.
