Quick update: We successfully installed the 235 in the '46 frame. It was a TCI MII full kit with power steering, installed to their specifications. The biggest challenge was the front motor mount interfered with the power rack. With maintaining the original engine and trans position we could not use the front mount - period. Not a big deal as we simply fabbed side engine mounts just as we would for a small block V8.
NOTES: A manual rack may have had enough room. Also, if we raised the motor and trans, we could have made room. Lastly, the MII cross member could have been installed lower in the frame, but this would raise the ride height.
Hope this helps folks with future projects. I have photos available.
