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

interviews Tony Hewes in this detailed HD video series. This segment covers the Jeep inline six 4.6L
stroker motor short-block configuration options.
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.
