but that combo could yet make another 50-75hp with the head ... even a stock head.

actually, i forget what car tv show did it, but they tried a self learning EFI throttle body on a 4.0 and it failed miserably. then Rock Hound Racing, the 222 buggy, runs a holy MPFI self learning computer to run his 4.7 stroker and i'm not sure he's ever made it thru a full weekend without if failing somehow. multiple iterations and he's now going back to a stock 4.0 computer. if doing EFI, rip it from a junkyard jeep.
