newly rebuilt sbc 400 1st problems

Anyone that has a hydraulic flat tappet camshaft should purchase some brand of Engine break-in oil. You can use Royal Purple, Brad Penn, Comp Cams, Joe Gibbs Racing. Now after break-in you can use your brand of motor oil (except synthetic) with ZDDP Plus additive added to it. There is no exceptions or you will wipe the lobes off you camshaft. Read this Wiki article on adjusting valves to make sure you are doing them correctly. Here is another Wiki article on tuning the advance curve for your performance engine. Also explains how to set your engine timing.
