Thanks,
The cleaner one is the one I ordered, when I thought my newcoming car has original engine in it. The dirty one came out from the engine my car has, the truck model it is, and the cleaner pump does not fit, it won't go deep enough for the cam to set agains the lobe and the pump surface against the block.
To my eyes the pic tells pretty much unquestionable the huge difference between these two. The correct one for my engine has the cam pointing from down to up, and the one fitting to "regular" 230cid has the cam in upper portion and it is straight.
I did try to install and see whether the cleaner pump fits but no luck. Feels like it doesn't settle against the cam lobe. Ofcourse I didn't try to force it, which I usually do when running out of brain...
Good thoughts, keep them coming, maybe someone has had an similar swap.
EDIT Doublecheked: No, they are not interchangeable. I measured the cam contacting point distance from mounting pad, and there's apprx. 3/8" difference in length. The cleaner pump which fits passenger 230, has the longer straight cam, and cannot be installed to my P25 engine
