Cleaning used short block

After you get it clean, I used that purple Castrol cleaner and hot water, then blew it out good with compressed air and let it bake in the sun for a few hours. Threw in some new rod bearings, a fresh double roller and a bigger cam, and then ran a quart or two of automatic transmission fluid with the oil when I got it running. That will clean it out good. Change the oil more frequently until it starts to stay clean longer. It dried out good.

It lasted over a year, and was still turning mid 13's when I took it out. It always had only 90 psi in the #2 cylinder. There were no cross hatch marks on the cylinders when I inspected the #2 cylinder. It was just a high mile motor that used 2 quarts of oil a tank.

The 408 that's replacing it is getting a little better treatment. It's amazing what a little cleaner, some elbow grease and some paint will do.
