Crankshaft

[trucker 46]

I HAVE QUESTION, is the 1948 crank interchangeable with 1946 in flathead V8 ? Thanks

1946 and 1948 Ford AUTOMOBILES with the 59A engines...the cranks are interchangeable. If the '48 crank came out of a truck-type 8RT engine, then no...that crank is different in that it uses different-type insert bearings, and the oiling holes on the throws will be different to accommodate such. 1948 trucks got the newly-designed engine one year earlier than the passenger cars did.

The 1948 8BA crank will also work in the 59A. You can use either the floaters with the 29A rods or 8BA rods with the tabbed bearings.
