HYD roller.What type of cam ?
Hydro cam & lifters don't need a break in period, just flat tappets..HYD roller.
Were you running steel distributor gears?Never had issues on a roller, even on the sprint car engines in 14 years.
No, steel gears can get you in trouble, I only use composits in my 427 Cobra engines and sprint cars. I also only use standard flow oil pumps.Were you running steel distributor gears?
They ( melonized steel on 6120-50-60 billet) require a specific break in period as noted above.
Especially relevant if running a high volume or high pressure oil pump.

You can use what ever just add a bottle of zinc or use oil with zinc in itWhat weight break in oil should I use in my engine? Thanks![]()
What's the cost difference ?You can use what ever just add a bottle of zinc or use oil with zinc in it
"'Valvoline VR is a typically available shelf oil fine AFTER break in''.Break in oil has a fast acting zinc package with lower detergent.
Simply adding ZDDP to any modern shelf oil is asking for trouble. Adding more zinc to any proper flat tappet hot rod oil is asking for trouble.
We've had several clients with new cams and notched lifters. The very few break in failure our clients have suffered all have the above in common.
Use the right oil.
Valvoline VR is a typically available shelf oil fine AFTER break in.
P.S.
We routinely break in dual spring flat tappet cam engines on the dyno with Gibbs Driven BR oil. NEVER A FAILURE.
Starts immediately, notched lifters for additional oiling from the top down and proper oil for break in.
DO NOT TRY THIS AT HOME !!!
Simply an extreme example of what you can do with the right procedure, hard parts, assembly products and oils.
