37 6 cylinder reassemble issues

Ok,,, I have started the reassembly on the engine, installed the rear main seal, and dry install the mains and rods to plastic gauge , mains were center of the bands, rods were less than .001 and more than .0005 inches.
So r&r crank,, lube with assy lube, using a breaker bar on the balancer nut to rotate the crank
commenced torquing, l did the mains to 85 lb and could could rotate the Crankshaft fairly easily,
Did the rods next after oiling the pistons and cylinders I installed the pistons and rod bearings.


TROUBLE arose.

I Figured torque was in the 45 lb for this engine.
Ok...
Problem
can only torque rod caps to 15lb and still rotate the Crankshaft,

So. Looking for some insights,

Crank was 10 under ground and I purchased the 10 over bearings.
Rod caps were resized for the late model 10 over bearings



My thoughts are to torque the rods to 15 to 18 pounds and install the cotter pins.
Run the car for about 100 miles and pull the pan and torque to 45 pounds, and check rotation,

I wanted a tight engine and it seams that's what I have.


Thanks in advance for your experience.
