My 4.7L stroker from Western Engine here in Denver has worked great for years. My last dyno had me at 336 horse power and 435 foot-pounds of torque @ 3400 RPM. That is with a cam, a lot of head work, exhaust work, custom chip, etc. It was not cheap. Even with all the extra weight on my Jeep it still gets up and goes.
I did it because I hydrolocked my 4.0L. As long as I was replacing it anyway, I figured why not. If I were just looking for power, and my motor was working well, I would consider just upgrading the cam. This requires pulling the head to get the lifters out of the way. Including a head gasket, cam, head bolts, fluids etc. you should be around $500.00 doing it yourself. It is a good weekend of tinkering with the Jeep.
