I have had very little experience with engine modifications on a '33-34 Ford, I do recall that the '32's had a bracket, a leg like affair, that bolted to the front of the engine and the front cross-member. I also recall that the majority of the later blocks, '37-48 were drilled at the factory for the earlier mounts.
In years gone bye I installed several '37-48 Ford V8's into '36-40 vehicles, never had to use a motor mount adapter.
The off-set in the bolt holes of the Merc adapter's allows the 8BA style of engine with Merc/or truck pumps to work in a EFV8 chassis.
