See if you can measure the breakaway and rotational torque with a inch pound torque wrench both ways. I use a old 1/4 inch drive Snap On brand beam type torque wrench with adapters to the 1/2 inch to the 1 1/4 inch or 1 1/8 inch socket size for those type measurements Back in the early 1970s Dick or Mike Landy recommemded having from 21 to 23 ft lba break away torque and 15 to 17 lbs rotational torque both ways That was with 1/16,1/16 ,3/16 low tension rings in both Hemi and wedge motors with 4.25 to 4.380 bore sizes Let us know what you get My current bracket motor has .043 steel top, .043 cast second and a 1/8 inch low tension oil ring, these are for a vacume pump motor also. I flat forgot to check the breakaway and rotational torque readings before assembling the motor It has really low drag though This baby should make a hoop of power, hopefully
I agree with you on using standard tension oil rings on street motors, even on a bracket motors with no vacume pump
I've had bracket race motors with teh smaller ring paks used today with standard tenion oil rings that I can rotate the crank with 6 pistosn installed with my hands only on the cranks, adding the last two rods and pistons make the breakaway torque more than my old hands and arms can do now AKA aside, low drag is good
