you need to be accurate as to which Sherman kit you select. I am not sure which engine you refer to as whirlwind (I'm assuming it's the radial engine) you would be limited to:
Just to pick the last nit, if you are actually talking abuot the Wright engine (based upon the Whirlwind aircraft engine) then only a very early M4A1 will do the trick as very early in the Sherman production cycle the Wright was exchanged for the Continental version of the same engine. Still a radial, but there is a significant difference in the engine pipework and the rear hull plate configuration. I suspect ou don't really care if it is the Wright or the Continental, in shich case, use the Continental as the vast majority of Sherman M4s & M4A1s were built with it.
Tank Worksop makes a fine Continental engine compartment for M4s & M4A1s. I think the Verlinden engine kit has accuracy problems, but don't hold me to that.

M4A2s used a diesel engine (I cannot recall anyone making this engine).
Tank Workshop make an M4A2 engine and, I think, an engine compartment with it. The Academy M10 kit also comes with this engine.

M4A4 used multiple engine
Known as the Chrysler Multibank. I have seen a resin engine and my little brain wants to say this used to be made by Tank Workshop, but I'm not sure I believe it this time.
