What's a good timing setting for a Olds 455 with Edelbrock cam it has Hei distributor with stock plugs, in process of changing the plugs to Ac Delco r46sx. my mechanic has the timing set at 20 degrees. just wonder is that's good.
also what brand oil filter are you guys using I like Ac Delco for my chevy motor. not finding a good Ac part number for the Olds.
