1949 288 Straight 8 Break In

Posted by FlippinMastaT On 2022/6/15 10:54:53

Hello,
Just finished rebuilding a 1949 288 Straight 8 engine and have fired it up. I'm going to run the break-in procedure next and since this motor is more unique than what I have rebuilt in the past I wanted to ask for any recommendations.

On previous motors I have initially gotten the engine up to temp, then increased RPM's to 2000 for 5 minutes, then increased RPM's to 3000 for 10 minutes, then decreased RPM's to 2000 for another 5 minutes. Shut off and change oil.

Any recommendations for this specific Packard flat head would be much appreciated.

Thank you.
