Shawn has the motor pulled down and PM'd me.
A couple things,measured your bores smallest part of the smallest bore is 4.0050
largest part of the largest bore is 4.0085-that's .0035 difference.Some bore had as much as .0025 taper and out of round-pretty much like every other SDxx engine.The pistons were 4.0005-so you had as much as .008 piston to wall clearance.
I'll send you some picks tonight but you can see where the main caps were walking around due to the stock main bolts.
It sounds bad but it demonstrates to me the Shawn will have it right when I get it back.
No wonder it didn't make any power.
