Smile new motor

I'm in the process of build an 354 / 5.0. With the crank, rods, pistons, rings, cam and timing chain installed it took 22 lbs of force to turn two rotations. I read that is should take between 30 - 35 ft lbs of torque to turn the assembly.
If you have the rockers / push rods installed then the pressure of the springs will make a big different. The lifter to lifter bore cleanance should be checked. If the lifter is to tight then hone the bore to the proper cleanance.
