I have a 1965 Sport Fury with an original block 426 and 4 spd. Haven't changed the oil since I have had it (but check it regularly), maybe 2000 miles has been driven. Edelbrock heads, intake and carb. 10.5:1 supposedly, dynoed at 408 hp at 5100. Old standard 10W-40, or a newer 0-20W synthetic?

Wandering around the internet, I can find multiple listings for this. Some specify Carter M3672, others M6866 (bid difference in lever arm length). Differences probably due to engine types/sizes? Which one is the right one, or what would you guys recommend?
