hard to turn rebuilt engine

I just rebuilt a chevy 350 with new rings, cam, lifter, and all new bearings. The cam spins easily by itself, the crank spins easily by itself, but as soon as a connect the rods to the crank and install the timing chain it gets difficult turn. (not impossible, just harder than my old 305 is). I heard it was normal until it gets broken in. Should i put it in the car and try to starts it up or what?

Should take about 30-35 ft lbs to turn it. Make sure you have the rod caps on correct.

Its gonna be harder with the with all the rotating mass put together with the pistons, springs, etc.. I have a 350 with about 40,000 miles on it that is far from easy to turn.
