Re: straight 8 & transmission interchange 1934 to 1937

The switch will not work. The '34 crankcase is cast with two "horns" which sit atop the frame rails. The 37 has no such "horns" and is mounted on an upside down U which sits on the front crossmember and attaches to the motor via a rubber insulated mounting to the timing cover.
The 120/Six are mounted in a similar fashion as are most models from 38 to 50. This is a result of the 34 with solid axle and 37 with independent front suspension and the vast frame differences.

The engines are quite different:

34 has chain driven generator and the crankcase casting is different,. 37 is belt driven and timing cover is vastly different
34 has oil cooler fed from side of water jacket plate, 37 is fed from a gooseneck on side of block.

I believe the crank, main bearings, rods, pistons, valves, lifters, cam rockers, lifters and possibly camshaft will interchange.

The transmission will fit both the 34 and 37
