Moses Ludel Vlog: Why Build a 4.6L Jeep
Inline Six Stroker Motor?
The Jeep inline six stroker motor is a popular topic! In this HD vlog,
Moses Ludel shares his many reasons for building a 4.6L Jeep inline six stroker
left is the predecessor to the seven-main bearing 199/232/258 and 4.0L AMC engine design shown at right. The engine at left
is a 196 cubic inch Nash/Rambler 4-main bearing design. The 1964 design breakthrough at right would serve AMC and
Jeep through 2006!

Performance 4.7L inline six stroker motor for Jeep models. At right is a 4.0L cylinder head reconditioned at the

Six, additional tuning recommendations that accompany a stroker six
build-up. For Jeep use, the real success story with the 4.6L stroker six is the torque output and
torque curve. Torque rises far more quickly than a stock 4.0L
and should exceed peak 4.0L torque by at least 50 ft-lbs! Most
of the torque comes in by 2,000 rpm, and this improves the real world driving feel and trail crawl
performance. Torque continues to climb to a peak in the 300-340 ft-lbs range by 3,200 rpm—depending
upon the build.
