I have finally put my GEN VI 454/TH400 in its home, but the oil pan is quite close to the crossmember and that is with a 1" shim on the transmission mount. I am using the stock oil pan, stock clamshells, and mounts. I have about 1/8" of clearance. Did anyone use the stock oil pan and not have clearance issues with the crossmember? Thanks for your time.

Yeah, something isn't right. I am using a stock replacement anchor 2360 transmission mount with a JEGS transmission crossmember and stock replacement OER 332648 clamshells and anchor 2292 mounts. If I try to set the trans directly to the mount the oil pan contacts the engine crossmember. I am starting to think the OER clamshells are too low maybe. I know others have used the stock oil pan but am having a tough time finding those posts.
The OER 332648 is listed as an Fbody clamshell, I don't know if there is a height difference between those and Gbody.

Is the Gen 6 oil pan deeper in the front than a Mark IV? When I first installed a BBC in my Monte I used the factory SBC 305 clamshell mounts and had no clearance issues.
Mine is also using the original 305 mounts. The engine came from a motorhome, no issues. It's a GenVI short block but with a MarkIV pan.
Mine came from a motorhome as well but I have the stock Gen VI oil pan. You switched to a stock Mark IV pan?
