I agree. there's a lot of crap to deal with when keeping the engine in the bay. you will have clearences to deal with like the windage tray. the pan won't come out with it in place and the frame is too close. how can a new rebuilt motor do that so early. do you have the proof of it being rebuilt with the list of the replaced parts?trw has a good pump. just make sure its primed with oil before you install it.
