It takes about 50-55 ft lbs of torque to turn the engine over. The cylinders probably have next to no oil on them so that could be part of the reason but still I didnt think itd be that hard.



That is going to be about right for a fresh engine.







Also, if you used moly on the bearing surfaces instead of oil, it will make a BIG difference in the break-away number.

Whatever I used was stuff they gave me with some new crank brearings for another engine I done. I unhooked the valvetrain and its showing around 40 ft lbs. I guess Ill run it... the cylinders all look fine. I did notice some of them have a grey powdery stuff on them now.. is that from the rings breaking in?

Gesh, start it up and forget about it. I haven't done an engine in a long time but I was so anxious to see if it worked I couldn't stand it. Check out my hemi here. Vroom, vroom Kim

Grey powdery stuff? I hope the pistons weren't installed dry. The pistons should have been oiled along with the cylinder walls prior to assembly. If not, it would be a good idea to take those pistons back out and dip them in oil. New rings and freshly honed cylinders will create drag and make the engine tighter, even with oiled walls. DO NOT start that engine with dry pistons.


I love the smell of Deer guts in the morning, it smells like... VICTORY!

do you know ring tension for each cylinder?
