Early Cad engine in 40 Ford

[Automotive Stud]

I put a 55 331 in my 40 convertible a few years ago. The 55 motor is the first year without the extended bell, so I wound up having to trim the flange off of the firewall at the very bottom just in the center where the toeboard meets. The steel trans cover still fits and covers the trimmed area it wasn't a lot. It's a pretty straight forward swap. The front mounts needed to be raised about an inch and a half to get the oil pan off of the crossmember and I had to raise the radiator to match.
