I have installed a few 351W's, and a Cleveland going in a friends right now. The 351M is a dog and not worth it as well as the Cleveland is designed for Nascar and not the street aside parts being very hard to get. The Cleveland needs RPM'S and not a good pick for the street *IMO..
A 5.0 and the earlier Windsors all INTERNALLY balanced,,,,,, period,,,,, differences in Mexican block, US. block and the 5.0 in regards to crank shaft seal, strength, etc, etc,,,,,, 5.0 blocks are roller cam but not as strong as early blocks... blah, blah,,,, good site is SMALL BLOCK FORD ("+???)a will post link after this,,
ANYWAYS,, the 351 is TALLER and so creates some issues with breather clearance in the doghouse, even if you do the advised box adding under the seats. I have one now that I need to change the breathers over to side type in order to get them to work,,,,
The Windsor cast iron heads all limited breathing CAPABILITIES and so I have dumped the GT40P heads because of limited header choices and the spark plugs. Had a hard time getting $150 for a brand pair that were like brand new??? LOL Replaced with some high end aluminum heads with all the bells and whistles.
In regards to using the 64 C4,, the bell housing is bolted using the pump bolts versus the PAN FILL C4 that has separate bolts from the bell housing to the case. The 64 C4 is a CASE FILL,, same guts.
You can interchange ANY C4 TAILSTOCK onto ANY C4,,,, they ALL INTERCHANGE... not hard to do. The 64 C4 using a DONOUT mount tail stock which is weak at its BEST,,, the reason I use an UNDER TRANSMISSION type mount short tail stock and my transmission cross member for the earlies. (earlies are 61 to 64).... duh,,,.
I DO HAVE the hard to find 6 bolt bell housing that bolts up to the "PAN FILL" type 4 C4 transmission which will allow you to use the pan fill on a small block V8 or a big six. I also have any Econoline transmissions and all tail stock in stock,,,,,LOL... any one you want I have it,,,,,
I also make the V8 cross members and a ton of other parts for ours from replacement idiot light lights to disc brakes,,,
