Marlin, I cant speak to the other swaps, but the 351w windsor swap in the Pantera is relatively straight forward. The bell housing pattern and all ZF interface is the same as a Cleveland. The motor mount locations are also identical. If you use an ordinary 9.5" deck unit, it'll take some mods to tour headers and exhaust. the only other mods to address accomodating the thermostat location and alternator and A/C brackets. If you milled the deck to 9.2" and used Cleveland heads you'd only have alt and A/C bracket differences.

Why? IMHO, the Windsor block is a better block. It has thicker cylinder walls, heavier webbing everywhere you want it, and big main caps. Even though they are only two bolts (unless your talking SVO blocks), they are very stout. Frankly, 4-bolt cleveland mains aren't much compared to other typical 4-bolt main caps. Windsors also have wider pan rails. My stroker is 4.100" and I didn't have to touch the block for rod clearance. The Windsor mian journal diameter is larger than the Clevelands and some say this can create high speed lube problems. It does however make a 400 crank drop in with only snout mods.
