My 1953 low pressure 235 is a 3701946 block, however it has the boss holes on each side for the car engine mounts. I actually had to 'drill' the two front mounting holes to install it. Unless all blocks came with the boss holes for the car mounts, I would question if a 3701946 block is only a 'truck block'.
