I "hope" someone out there has an answer. I went out and bought a World Castings "Merlin III " block...right from the factory warehouse.It is a big block 427 block,4-bolt main. The problem that I am having is that I can NOT get a oil pan on the engine !!!
The back of the pan is hitting the back of the maincap and the oil pump housing.It is not hitting the pick-up. I have tried a Rick's First Gen pan and a Moroso pan...still hits.I called World Castings and they swear that I do NOT have one of their blocks...they have quality control...bla bla bla. They won't own up to a problem.The block DOES have Merlin III embossed right on the front of the block and was a new one.Problem is that I have a $21,000 motor sitting here that I can't put a pan on.An 8-quart pan will not help.ANY suggestion or help would be GREATLY appreciated!!!!!!!
