83 CJ engine upgrade

I have an 83 CJ with straight 4 GM 151. I want to upgrade to a V6 Is there an easy replacement engine that will require little to no modification to the bell housing or Tranny?

Which transmission do you have?

The CJ forum has a lot of info on these. Do a simple 151 swap search and a bunch of info will pop up. Also Novak http://www.novak-adapt.com/index.htm has a lot of info as well. Pretty much any swap will require some change to drivetrain somewhere. If you have a weak transmission to start with (sr4 for example) keeping that would be silly after spending the effort to change the engine. I believe if you go to a GM motor you can still use your bellhousing.
