No, but they will fit the same. The B shaft is undercut between the bushings to allow more oil flow. This can be done on a lathe to an A shaft.

J Franklin is correct, see November 1932 Service Bulletins.

Will a model A distributor work okay in the model B engine?

No problem, that's what I'm running right now. You must make one change to your timing procedure: instead of setting the timing with the spark lever all way up(retard) put the lever 1/2 way down.

Kong Jackson, Ed Winfield and myself in 1976. B engine, 39 transmission, model A rear end in a 29 roadster pickup. That is a Cook four port head with a one of a kind Kong ignition. the other side of the engine had two downdraft Winfield carbs.

Wish I still had it

gmdy, I still have my Cook, last ran on the salt @ 167 MPH, on alky, with a turbo. Steve Serr of Miller hi-speed is in the process of producing a repro, improved Cook.

Wen I put a ModelB engine in my Model A, instead of cutting the model B oil pan, I enlarged the semicircular opening in the rear of a model A oil pan to fit into the cork seal channel in the Model B rear main cap. Worked fine.

Model B oil pumps shaft were cut down to a smaller diameter between the upper and lower pump bearings to improve oil flow in the pump body. Model A shafts were straight.

In England all "B" engines were serialled on the block pad . The law required that the engine itself must be serialled . AA trucks in England were built into 1936 . I had a 1935 AA with AA 4981139 stamped on the block . These engines had a "B" oil pan with no shroud attached . This is just to clarify if someone has a "B" engine which has a serial on the block ,they are a more robust engine than the Detroit engine with a thicker top deck and are not prone to cracks anymore than a "A" engine .In WW2 they were used in welders ,generators etc etc and some ran on kerosine with cast iron pistons and special exhaust heated inlet manifold . More astounding useless information !!!

John,thanks for that interesting history. The Ford flatheads had the number on the transmission housing. Did they fit under the same rule? 32 on.
