I'm building a 440. Hughes cam: 2024BL. 220/224 duration .503/.518 lift at valves. At installed height, valve springs are 150-160 lbs pressure. A friend told me that this is a lot higher than stock 100-125 pounds. I spoke to Dave Hughes and he is pushing Joe Gibbs break in oil for ZDDP during initial break-in and Joe Gibbs Hot Rod oil for ZDDP for use with flat tappet cam and high pressure springs during daily driving. I bought the Joe Gibbs break-in oil.
I drove a Hughes cam with Hughes springs in a 360 for 10 years from 2004-2013 approx. Ran with conventional motor oil. Not a problem ever.
What do you think of this ZDDP issue?
What motor oil are you using?
