My original pan was unuseable so I bought another one. It has straight side rails and good threads and is in good shape.
It does not fit the rear bearing.
Murray Fahnestock says to straighten the pan by attaching to the block and using wood block and large hammer.
My concern is will that damage the block. I need to move it a little over 1/16”

Re: Crankcase fit on 4th main
how i do it. mount pan to block in the VERTICAL position before gaskets. Place 4th main down watching for uneven contact . if not perfect, i bolt a 4th main core upside down & persuede the back of the pan in the proper direction with a #4 dead blow hammer. The extra 4th main is to protect the pans shape. recheck between adjustments with your new 4th main. 1/16 is easy.

Re: Crankcase fit on 4th main
I have rarely needed a pan jig. In fact a local guy that has a pan jig has never for me produced a straight enough pan. So even if you have a pan straigtened."trust but verify"

Re: Crankcase fit on 4th main
When I took my engine apart, the 4th dropped in and out just fine and holes lined up. While the pan was sitting waiting for the babbitt it kinda relaxed. Except for the head and hogs head the engine was assembled when I found out it was off a little. I put a block of wood on top of the block and sat a jack on that, then ran a chain over the top front to rear and pulled the rear back up the small amount it had dropped. I did bring if up a little more then needed and when done, the 4th dropped right in. 
I know the voices aren't real but damn they have some good ideas!

Re: Crankcase fit on 4th main
I resorted to a similar process to Mark. On my 1915 pan, which I first set up on a pan jig to check for straighteners, it was perfect when I had finished with it. On assembly, the fourth.main was 1/16+" out. Before tearing it off and having another try, I let it sit for a day or two while I considered the problem, and came to the conclusion there was nothing I would do differently. So I used a jack and chains to persuade it to fit. The early pans without the rolled edges are prone to easy flexing. I Checked again with the motor vertical on the stand Before I was happy.
