Would you guys break in a flat tappet engine the same way or would you break in the cam then beat on it?
When we dynoed my engine the other week I asked the guy running the dyno about break in he just looked at me...Like I said earlier, get it up to operating temp (moderate load), then stand on it. If it isn't going to take it due to excessive tight clearances, it never will, no matter how long it gets ran.
Why no synthetic? 700hp corvettes get it from the factory and never have an issue. Why would other engines?
