While I slowly progress on the re-assembly of my '66B, my restored engine
still sits patiently on a stand waiting to be put back in and fired up.
However, today I noticed something that I'm hoping isn't REALLY bad.
With the plugs out, I hand cranked the engine (it's been sitting now for
almost 7 years...my how time flies...so I like to spray a little lubricant
in the cylinders every once and awhile) using a torque wrench and a 1-5/16"
socket. Generally, I found that approximately 25ft-lbs of torque was
required to turn it except at two short intervals within the complete 360
degree rotation when the torque dropped almost in half. The two intervals
were 180 degrees apart.
I had a machine shop overbore the cylinders and turn the crank, but I
installed the new, oversized (but for the life of me I can't remember how
much) bearings and pistons (0.030 oversized). I used Plastigauge and
verified that all the big-end bearing clearances were in spec.
Is this a problem?
