Like a kid at Christmas, I just acquired a truck load of flathead stuff. It is all 49-53. I think I got a merc engine. It is disassembled, but the back of the block looks like factory merc green. I got 2 cranks, 8 heads, all the bolt on stuff twice. It looks like I got 2 engines short 1 block. I also got 2 top shifter transmissions, flywheels, clutchs and press plates, 1 radiator and a box of bolts, valves and misc. He told me to wait and he would see if his wife had not thrown out some gaskets. He had about 4 sets of head gaskets and about 4 or 5 intake gaskets. Did real good on the price and he was pleased also. I want to be on good terms. He has a 63 T Bird sitting in the barn. The engine is under a tarp, 390, but he said he rebuilt and never put it back in the car. Real nice guy, a diesel mechanic, retired. Anyway, need to check the cranks and see if, I got real lucky or just lucky.
