Thread: break in on chevy 350

To seat the rings you want to put some load with it. My ZZ502 manual says to do 4-5 half throttle runs from 30 to 60 letting off in gear each time back down to 30 and repeat using 3/4 throttle. Then drive normally for 500 miles, this establishes the proper wear patterns.

no synthetic. used sae 30 for the 50 miles then changed oil and went with 10w 30. thanks for all of your help ill just continue to drive it and im sure over time it will be fine. The 104 im running at 5.50 a gallon kind hurts the checkbook tho. The carb is a little bigger than i need i think except for under full throttle I've heard its ok, I need like a 750 i think, but cant spend the money for another new carb just yet.
