I have modified a Model "A" oil pan to it the Model "B" engine in my Coupe. Here's an overview of what was done:
> The cutout for the rear main bearing in the back of the pan needs to be enlarged. Make the cutout just large enough to squeeze the cork seal that sits in the bearing;
> Using a ball peen hammer, put dents in the side of the pan to clear the connecting rods by at least 0.13". The Model "B" has these dents;
> A couple of oil pan attachment holes in the block will not lineup with the bolt holes in Model "A" pan. Leave them out;
> Make sure that the scoops on the connecting rod caps clear the tray in the oil pan. I used the Model "B" tray because like the later Model "A" tray, it sits lower in oil pan;
> Use the shield on the tray that covers the oil pump;
> Be sure the drain plug boss is soldered / brazed to the pan so it doesn't spin / leak;
> Use self-locking modern nuts on the rod caps to eliminate the stock castle nuts and cotter pins. Be sure the modern nuts have the same number of whole threads or more because the strength of the nut determines the strength of caps retention.
