My rotating assembly is hard to turn once the rods are torqued down. Suggestions? Last year I had a bad cam bearing in my motor (LS1 block, forged 347) so I pulled it and had the block all checked and a new cam bearings installed.
Well, I got around to installing the crank, rods and pistons yesterday. When I installed the crank and torqued down the mains it spun very easily and freely. After I installed the pistons and rods it was a bitch to turn. It's the same rotating assemble that came out of it. I didn't change anything since the motor only had 150 miles on it before the cam bearing went bad.
I pulled the rod end caps back off and the crank moved very easily again. Reinstalled the rod end caps and torqued them down and it was a pain in the ***. I can't find anything binding at all. Is it supposed to be this much of a pain in the *** to turn over on a new motor or do you guys think I am ******* something up?

Although I did notice that only 4 of the pistons have front marks on them. The other 4 do not. My old Wiseco pistons all had arrows on them. Not sure why these aren't like that.
