Oil pan hitting the center linkage.

there is a later model pan that will work (369 ?)-- also you can shim the passenger side motor mount & that will raise the engine up a bit to clear ,while your looking for the center link-- what happened to the pan on the engine removed? -- good luck Lawrence

X2, I made several small square 1/8" thick steel shims for the mounts in my E-body a few years ago, put a couple in each side - made just enough difference to allow clearance.
