Can someone explain me what to do on breaking in my 261 with m4f cam, standard intake and exhaust(for now), .030 overbore and 848 head?
I allready learned that after priming the pump i should rev the engine up to 2000 rpm for the first 20 minutes (fast idle). But i still have questions after that.
When should i change the oil the first time, and what to do after the first 20 minutes?
Thanks
Dennis.
