5.7 Crank Tight Spot

You could use a very light torque wrench and spin it snd see how much increase there is. I think you should be able to find a number that it should require to spin and then an amount at the completion of piston installation.
SBC would be around 15-25 ftlbs with the crank installed and 35-40 with the pistons in. Yes, old info, and relatively stock components, but the point is the same.
