The Ford Barn

I have an 8BA I ran in a '32. I replaced it with a more period correct 59 AB

So I would like to run the 8BA in the '40 while I have the original engine out for rebuild.

The 8BA already has truck water pumps on it, and I have the radiator hose adaptors. But what about the fan. Can I use the '40 fan and crankshaft pulley on the 8BA ? Any other issues I haven't though of ?

1 more thing, what late Ford or Merc cylinder heads have the highest compression ratio, and how much can you mill them with out interference with the valves with a stock cam. If need be, I will run high test, octane booster or AV gas.

Thank you Fordbarners,
