377, 393, or 408 stroker?

I'd say the best compromise of durability and performance would be the 393. It should have a better rod angle than the 408 and a tad more power the 377. The oil control will depend on the piston design. As you'll see on some builder's website's, a lot of company's kits have pistons in which the oil control ring intersects the piston pin. This is fine for drag cars, but street cars need the oil control. Try to find one with a piston designed so this intersection isn't an issue (like DSS or Coast High Performance). Also, check out the specs like the rod/stroke ratio. It's too difficult to explain and I'm not even sure I understand it well enough to give a good explanation, but just remember that higher numbers are better.
