Can small block oil pump be replaced without pulling the engine?

I've done it several times;
68 Barracuda, 360 4-spd on a 70 Duster K with biscuits. TTI Headers, Milodon Road race pan (with tray) with the side bump-outs, and steering from a 73 Dart.
On my back of a cement floor, or on a 4-post.
Either way, I thought it was pretty easy.
on this Barracuda, I think I did that at least three times maybe more.
Done it on other 67 to 75 A-bodies too, with SBMs, but with stock pans .

A tip for reinstalling is to put a couple of line-up bolts, one on each rail with the heads cut off and the shanks slotted for a screwdriver. Then it's just a slamdunk.
Don't forget to pull the dipstick out before you start, and Disconnect the Battery.......
