So, prior to priming the oil pump and oiling the block with it... it was nearly impossible to turn the rotating assembly. After oiling it it takes about 80 lb ft of torque of initially start spinning the rotating assembly, then once it starts moving it takes about 65 lb ft of torque to rotate it.

Is this normal? Or is something wrong?

are the heads and spark plugs in when you try it??

this is off topic but, a few year ago a friend re-built a motor with 30 over rings he got at auto zone. When he went to crank it, the motor would barley turn over. He took the motor back apart and found out the rings were 60 over. The company stuck the wrong size rings in the right box.

Unlikely but, it could happen.

This is on a short block. just the cam, crank, pistons, flywheel and balancer.

It is very easy now compared to before oiling the block by manually running the oil pump. At the time of assembly it took about 30 lb ft to turn the rotating assembly. The wrist pins are stock. Everything else was redone.

did they not use assembly lube??

Yes, it was used. Cam and bearings installed by a machine shop. Cylinders honed, crank plastigauged, new freeze plugs, hot tank, and decked. Maybe more that I can't think of.

I mean, it's not really hard to spin the rotating assembly... I'm mainly concerned for my starter. I don't know its capacity/durability. It's a high torque mini.
