Naw Red! anything that burns fuel and turns the tire in pleasing manner, we get invloved in. Is the 401 not repairable? Is the Cherokee an "S" model or? And is it full time 4WD? THere are some considerations to help the dogyness of any combo and I wish for you to have succes if you do go the 350 route. I caution that some of those drivetrains created a very doggy scenario and some changes can be made to wake it up with which ever combo you run.
