My 2000 Dakota 4.7 has been having low oil pressure issues. I removed the motor and sent the crank out to be reconditioned. Everything looked ok as far as the bearings and the crank journals but I had the it turned 10/10 just to be sure. I used a local machinist who has done work for me in the past and has always done good work. I dropped the crank back in with new bearings and it rotated fine by hand. But as I was doing the rods it got progressively harder to rotate the assembly. I was concerned but really didn't know how tight I should expect it to be.
Now with motor back in the truck and everything is hooked up the motor isn't turning fast enough to start. It's definitely not a dead battery and the starter is new. I did notice the battery cables get VERY hot while I'm cranking it over. I'm going to double check my timing to make sure I'm not cranking against compression but I'm real confident that's not the problem.
What should I do next?

Any suggestions GREATLY appreciated.
