I am in the middle of my first Ford rebuild and the first of any kind in 20 years. I have an '84 351W HO. I just had the crank cut .020. I am in the process of putting in the new pistons using the old rods as they were from a recent rebuild that someone put in stock pistons into a .030 block. But I digress. I have pistons 1,2 and 4 in with no problem. I skipped 3 and 5 due to an issue of broken rings that I now have to replace. When I put 6 in and torqed it to specs it bound. No amount of torque could turn the crank. When I loosen the rod bolts to about 35 ft lbs it again turns freely. Does the new rod bearing size effect the rods themselves? It has been a long time and any help will be very much appreciated as it is getting cold here in Pittsburgh, PA and my garage isn't heated!!! Thanks in advance, Kruzer214
