Jeep 4.6L Stroker Motor Short-Block: Pistons, Rods & Block Configurations

This series includes six HD video interviews with Tony Hewes...In addition to the video on this page, you will find the other five HD videos at the '4WD Tech How-to Channel' playlist!

     When building the popular Jeep stroker six with a 4.0L block and 4.2L crankshaft, there are options. In this HD video, Moses Ludel interviews Tony Hewes of Hewes Performance Machine. Tony discusses two distinctly different approaches, one using 4.2L connecting rods, the other using the 4.0L rods. Tony describes the available piston choices and block machining approaches for each method.

     Today, there is a high likelihood that Jeep multi-purpose trail and highway users will rebuild a 4.0L into a stroker six. The gains of a high-torque, fuel efficient 4.6L stroker inline six build-up are proven. If you have a Jeep CJ, YJ or TJ Wrangler, XJ Cherokee or a ZJ/WJ Grand Cherokee with a tired inline six, consider the stroker motor rebuild. Beyond the cost of a 4.2L style crankshaft, the rebuilding cost is virtually the same as a high quality rebuild of the stock 4.0L engine.

     In this HD video, Tony and Moses discuss the key elements of building a stroker motor (4.5L to 4.7L, determined by the machined bore sizing) from a 4.0L Jeep inline six-cylinder engine. Learn the critical choices and how a precision shop like Hewes Performance Machine builds this engine.

     If your Jeep requires this level of performance and reliability, consider the machine work and craftsmanship available at Hewes Performance Machine at Reno, Nevada.
