4.7 V8 swap?

The Grand cherokee I got ended up needing the engine rebuilt. It was easy to do but the cost of the parts sucked. It would have been cheaper to buy a crate motor.
The only thing I didnt like about the engine was the lack of cam bearings & #8 oil drain design (in the top of head). The oil accumilates at #8 and plugs the lifter and also #7 #8 connecting rod seem to starve for oil compared to the rest of the rods.
