My two cents. A stroker from Bishop-Buell. No smog issues, no fitment issues. Stock, good condition cooling system will cool it just fine.
Russ built one for me, and I couldn't be happier. He will take the time to find out what you plan to use the engine for, and build it accordingly. I wanted low end torque, and didn't really care about overall high RPM horsepower. I ended up with an engine that can pull freight trains at 800 RPM, but is pretty much done at 4000 RPM. It sits in front of an AX-15, and I can pull Cajon Pass, loaded for camping, at 65-70 mph in 5th gear. There's even enough left to accelerate, albeit slowly. My fuel economy went from 10 mpg highway to 17. Off road went from 8 mpg to 12. Gomer is not a light Jeep.
I's also amazing to compare the power band of my motor to the one in the Team
4643 race Jeep. The two engines couldn't be more different. Same block, same builder, everything else different.
