I am not familiar with ford motors, but on Chevy and Pontiac if you bolt a bigger cubic inch motor head on a smaller cubic inch motor you will loose compression. the compression chambers will be bigger for the larger displacement engine and depending on if it is a high or low compression engine, when the heads are bolted onto the smaller motor the compression will drop significantly. I know it's not good news, but hope it helps.

Yes, it can be done. The swap is referred to as a -CLEVOR-.

It is not cheap as you will need Cleveland style pistons, a non-production intake manifold and some machine work.

I believe you will be better served to look around for a set of small block take-offs that will get you running, or put the complete 351M in the truck.

As stated in can be done. Stock cleveland (351 pistons will work and there are a few intakes that are designed for the swap, we called it the Bogus Boss back before Ford started releasing all the trick heads. The cleavor is actually a block designed for Cleveland heads but with the oiling system of a Windsor (much more mahvelous than the Cleveland).Unless you've been collecting Ford stuff for the last 30 years or know someone that has the swap wouldn't give as good a result as a good set of any of the current aftermarket Windsor heads and would probably end up costing the same or more.
