you might consider going with a slightly smaller cam, maybe around .510 or .520 lift, keep your compression ration you come up with. seems a bit overkill if your not revving over 5500, plus you want torque torque torque, down low in the powerband if your going off-roading. I'm assuming thats what you'll be doing with your jeep aside from daily driving. Comp has an Extreme Energy 4x4 series that has a cam perfect for you, Hydraulic-Great mid-range power, largest cam for stock converter. Good for heavy towing with 4.10 gear. 218/226 duration .505/.515 lift. Probably has a decent idle too. But that my two cents. I'm building almost the same motor, but its going in a street driven 84' shortwide Chevy that will see some track time. I'm milling and decking but i'm stuck with flat tops so I have to, just to hit 9:1. My block is a 4 bolt, with 781's, 2.19/1.88 valves, Edelbrock 2.0 manifold and a Demon 800 double pumper. I still can't decide on the cam but probably no more than .550 lift, should be a nasty little torque pig with lots of grunt, good luck with your buildthe reptilian brain is now the one involved
