Default oil pump change without pulling engine?

1985 2.8L, 4-speed, 2wd. Any words of wisdom? Can it be done? Best way? My pump is crapping out on me. Doesn't really use oil or smoke but oil pressure is getting down there. Any help would be greatly appreciated.

That's kinda what I figured. I thought I heard of guys doing it before but it seemed a bit unorthadox. If I'm going to pull it, may as well drop in a 3.4 or the 350 in the corner of the garage. Of coarse that leads to a lot more so I'm almost inclined to stick with the little six for ease. Just pep it up a bit.

I dont understand what the deal is with the 2wd oil pan removal. Other than dropping the front axle, my 4x4 was a cinch (just time consuming). Once the axle was out all I had to do was undo the inner tie rod ends, remove the cross bar to the idler arm, and the starter motor. The oil pan came straight out. BTW, how long does it usually take to get oil pressure back after re-installing the oil pump?

if the 350 in the garage is a carbed motor it would be a simple swap outside of mounts.. wich i think 88jimmy still has his for sale new and under cost..

and maybe flywheel/tq converter but the trans will bolt right up to the 350

I was under the impression that my trans would not bolt up to a sb. One from a 4.3 would but not a 2.8. Thought it was an odd breed. ??
