Hey friends, I have a little issue. I'm assembling my 440 and have run into a snag. Having followed the directions of my handbook, the advice of my engine shop and common sense, I am stumped. After installing new .040 Speed Pro pistons, new bearings, both mains and rods, and installing the camshaft and timing chain set.... the thing wont rotate. Not by hand anyway.. If I don't torque down the rod caps I can turn the crank with a 4 foot cheater bar and rotate the cylinders. It's tight but spins with out any noticeable hang-ups. I used assembly lube everywhere, lots of it. Oiled the cylinder walls, floated the pistons and connecting rods in engine oil, 100% synthetic oil...Everything is spotless. As soon as I torque down the rod cap nuts to 45 ft lbs it freezes up and wont spin. I don't want to break anything but what now? Loosen the rod cap nuts and it will spin. Is it a combination of all new bearings, rings and pistons? Thoughts please. Ghost.
