Cold Starting Long Standing Engines

Post #5 and #7 are sure to cause more trouble than you could stand. Please disregard them. posters please delete them for the good of all humanity.

Everyone please read that these are new never fired engines. This is not.

have you ever broken in a New camshaft? This is what you need to do.

specific to the 273:
*Do you know what product if any you put on the cam and lifter faces? Might need to clean it off and recoat depending on your answer.

* Use a modern Engine break in oil.

* Remove the distributor drive gear and prime the oil pump with a drill running clockwise. Rotate engine twice by hand so the rocker arms& shafts get filled with oil. You will need a helper. Run the drill the entire time. When completed them remove valve covers to see all rockers full of oil. If not find out why. This reduces the huge mess.

* Fill carb float bowl with fuel so it will start right up.

*have enough gas to run it for 25-30 minutes without shutting it off. RPM varying from 2000-2500, never below that.

* only have the water pump belt on, remove the others so there are no problems.

this will get you started. Question on the little engine, what is he camshaft, in block or overhead cam? Do you know of a way to prime the oil pump. It’s very importatnt, don’t skip it.

Do this startup when you and the car are ready to go for a drive afterwards. Don’t wait or let it cool down, go drive it. The breakin oil can stay in for 500 miles after the cam break in.
