My Engine builder likes the JoeGibbs BR oil as it is a break in oil that has the most Zinc and moly and what ever other junk they throw in there. and he lokes the Moroso filters.
i havent seen one of his motors come appart................ for what's that worth.
personally i would choose synthetic, i used to use Torco i back in the day and tere was never any wear showing on the bearings.
