It would want to be a very special 302 Clevo.....
Don't get me wrong, I love Clevo's, I run them in a 9 second Dragcar, in a 10 second rail, and with a big supercharger and 400ci in my F150.
But if you are only goin to sell the Windsor for $900, to go backward in cubes, bigger and heavier in the front, similar power to what you have now, and loose your extractors for manifolds, I say you are mad.
Sell the clevo for a quickie home freshen up of your Windsor, new rings, pistons, bearings, gaskets, cam, lifters and springs, with a good alloy manifold, should wake up the sleepy 351W. and you will still be in front, more power, good handling, less work, and you can still work on it.
My $0.02c worth.....
