What is the recommended rpm schedule for the 6BY2 during the first 50 hours. Is there any need to warm the engine up or to allow it to cool before shutting down. Thanks
 
I have the 4BY180, the recommendation I got and did was stay at varying rpms for half hour intervals with about 10 minutes at 80% of max rpm. I now have 262 hours and no complaints. The important thing is to change the oil at 50 as well as the transmission oil and screen.
