Now here is some advice I need to work my way through the dilemma. Right side mount has been installed with a welder. Hmm is that a Texas or a "Team Knuckle Duster" mod? I wonder? I can not even trust the engine location, my instinct tells me it was lowered down until things touched, the trans mount was installed, 1/2 steel plates were put under the engine mount to help the sump clear and the arc welder was used to glue it in to place. This is the stuff I need advice to fix properly.Double checking a few things, there is a difference between '90 & older vs. '91 & newer (per you gen BBC) with oil pans but the pick up looks to be good. With the difference with the pans you'll have to look into an aftermarket. But before you start digging into ordering everything suggested ensure the motor install is done correctly with the frame side motor mounts are bolted in the correct location with the correct mounts (same as for a SBC). Just getting the correct mounts could place the motor where is should be & won't need a pan swap. Another issue which I should of brought up in the last post was if the pan is an aftermarket 5 quart. Even possible just it being a 5 quart pan may just be the issue. A 4 quart would be a bad pan to use if it's all about the needed clearance.
