Some head-to-head comparisons...

Per the 4-ball wear testing, and Marc Haibeck's recommendations, my choice has been the Amsoil 10W-40 full synthetic. I've NO chain rattle after the first couple seconds after the engine starts. Once oil pressure is up, there's no rattle...ever, consumption is typical for a 90 LT5 with seals installed on all valves (modification via Marc Haibeck).
