center link hitting oil pan help

Morning, (at least it is here right now), I just finished an engine swap from a 1973 383 engine in my 1970 cuda to a 1969 440 engine after rebuild. I have been driving the car now for about 700 miles and it started leaking oil (spots on the ground). There was no sign of any oil leak for the first 300-500 miles. I put it up on the hoist and saw that the center link was rubbing against the oil pan. Could be slightly hitting there also, although there is no indication that it is. When up in the air, there is about 1/2 to 3/4 inch clearance between both. Can't really see how much when down on the ground though. The engine has a stock oil pan and the center link is also. Not everything is perfect in an engine swap I know, so here are my questions: how can I get more clearance between the center link and the oil pan?
Is there a different oil pan I can purchase that gives me more clearance? Can I do something to the suspension to give me more? Boy, any help will be greatly appreciated. BTW, before writing this, I did tighten up the pan about 75 miles ago and it started to leak around the pan again so I already tried that.

Thanks in advance.....
