Since you have 4 wheel drive I would just put another 46RH in it. Spend your $500 and rebuild it some some quality clutches. It should live fine and you won't have to reinvent the wheel trying to get something else to fit.

Using a 4.25" stroke crankshaft in a 400 block is really all the stroke you can, or should put in a 400 block. You just run out of available compression height for the piston with any more stroke at a 9.800 deck height. With a 4.375" bore that will yield 511 cubic inches. I don't know why...
Personally I use:
VHT SP188 Ford Argent Silver Wheel Paint Can - 11 oz.
I would post the Amazon link, but this forum will delete it. Just copy and paste the description in the search.
I used this for years on dozens of wheels. Much better than previously mentioned products.

Like when you drive by the Lamborghini dealership. It's reckless beautiful art. The maintenance is too much. You want to be in it, but you can't afford it.

Do tell
I would be very interested in that if you still have it around.
No, and thanks, but that's not the type of setup I am after. It has to be a factory built short tail housing with a slip yoke.
That way I can still have a governor and a parking paw on the output shaft over using the A&A...
OEM 351 Windsor block is 9.500"
That is incorrect.
OEM 351 Cleveland block has a 9.200" deck height
OEM 351 Windsor bock has a 9.500" deck height
However the hot setup is buying an aftermarket Windsor block with the 9.20" deck height and 302 mains if you want to race.
