Thanks for the info. I am rebuilding a 1946 pickup. When I bought it it had a 1950 motor in it. The motor is badly rusted with the pistons locked up in the cylinders. One of the cylinders has the side blown out of it, so needless to say, I need a replacement. I would like to replace it with a 1950 or later motor so that the transmission and bell housing would still bolt up. I appreciate any help.
