What is everybody's methods for running in a new top end. I've nearly acquired all of the parts to get my 351/346xp up and running. Historically I've had mixed results. This is my first new OEM top end. Most all of my other builds have been Meteor or Golf pistons in re-used and re-claimed burnt cylinders. I've gotten anything from small scratched to full on destruction. I don't know if its a cleanliness thing or something else. I typically let it idle for a bit and once warm give it juice. A few small cuts and then go big. Best results were with a new Meteor cylinder and piston that was let idle for most of a tank of gas before touching the throttle. Still some light scratches in the piston. None of my problems are from being too lean. What is everybody else's technique for running in a new top end??? Let me know. Thanks!!!
