the water passes through the intake on a Windsor and through the block and heads on a Cleveland. Therefore the Windsor has the thermostat housing bolted to the intake manifold and a Cleveland has the thermostat housing bolted to the top of the block. If it is a Cleveland(being they are no good) I would consider buying it. Let me know what you find out.

Don't bad mouth the cleavland too much, they can run hard but the parts are a little more expensive. A windsor looks pretty much exactly like a 302 except it is taller and wider. Basicly you can look behind the dizzy where the block meets the intake and see how big that wall is. The 302 is small and the 351 is pretty tall. You will probably see more 351 modified's than you would clev. so watch for those.

The 351C is a fine motor. Probably a better factory race motor than a Windsor. Differant sized mains, better oiling, differant cooling, etc.
The 4V engine has heads that are better for all out performance. But the ports are so big that they're difficult to get good power out of them in the lower rpm's where street engines work the most. The 2V heads are better at the low end, but give up a lot on the top end. Aftermarket heads will split the differance; but your choices there are a little bit limited.
But it depends on what your plans are. If you want to swap it into a chassis that never had a 351C, you might have some trouble. Getting motor mounts and headers to fit could be a real problem. Check in to those issues before buying it.
IMO, the Windsor makes a better street performance engine. Swap parts and speed parts are readily available. With just a little effort and carefull parts selection, 500hp is easily doable on pump gas. 600hp is not that difficult either, just more expensive.

I agree, I have one in my 90 hatch. It has 2V heads ported. Stock rods and crank and stock stroke. No power adder and runs 10.70's on pump gas drive it anywhere. 302 engine mounts and tranny bolt pattern are the same. The only thing you need is headers(heddman or hooker) and a rear sump oil pan and you are good to go.
