The Ford Barn - View Single Post - Retro fitting an 8BA crankshaft into my 42 block?

The 8BA crank should drop right into a 42 block, using the early main bearings. I question the fact that it's a 42 block. However, Red's headers makes a conversion Kit for this application. Also these early blocks had a different size main journal diameter.
