I read through the responses in the thread attached to this inquiry, a lot of verbage that did not really answer the question.
Putting an 8BA/8CM engine into a '35-36 Ford is a pretty straight forward afternoon job, if you go about the job correctly, in a few words, don't try to "re-invent the wheel".
I have attached a couple of pix showing a 8BA engine in my friends '37 Ford, other than issues that might arise with the clutch and the choice of exhaust manifolds, I would suggest that you use the stock '35-36 manifolds to maintain clearance on the steering gears..
In years gone bye I have done several 8BA swaps into pre '40 Ford vehicles.
The one big problem is the 8BA engines are not drilled for the stabilizer rods, a bracket can be made to bolt to the bell housing that will allow the rods to be attached..
