You better take a look at it. You should not see anything with just hand rotations. I always use the oil pump to pull the cradle forward before torquing the girdle down. Better to find an issue now rather than after its installed. Could be a mis aligned main cap that walked. or ?? Also make sure the thrust surfaces of teh crank are polished as well as the journals. It has been missed in the past.
Also I watched a couple vids and the clearance you are wanting on the piston skirts is .0045 to .0055. I would also look into the torque spec on the rods. From all the ones I know of it is 43 pound ft with those rods and bolts.

Piston to wall clearance was .0050, i just screwed up in the video.
I'll check the rod bolts as well. I just hopped on Eagles website and it looks like the under head length of the bolt not just the head size and material matters. 1.500" is 43 ft lbs, 1.600" and 1.800" lengths are 75 ft lbs. I must have looked at the wrong ones? Nice catch.

Ok guys, finally another update. I screwed up when i was talking about the rod bolt torque, it should be 43 ft lbs not 35. Finally starting to make some more progress and will continue in the coming weeks.

Well, I had to tear it back down last night. Even after using the oil pump to line up the girdle I was only seeing .004" crank end play.
I took ot apart, removed the sealant from the oil pump and cleaned everything up real good. Reassembled and still .004". It felt really tight and took some force to even get that much play.
Per anothers recomendation I tore it down again and lightly sanded the thrust bearing, just a few strokes on each side with 600 grit. Finally looks right after reassembly, .007" end play and a nice audible click when sliding back and forth.
Hopefully that's the last time I the bottom end comes apart for a while!

100 ft/lbs is on the edge of pull out. Should work if everything is good but very little margin. I would probable back it off a bit. I have been using 87 ft/lbs.

It's been really hectic lately but I made some time to get a little more work done. The oil pan mods (LR baffle, pickup tube extension and IJ pickup tube support) were installed and the oil pan was bolted on. I also got the long block cleaned up and painted. It's basically complete now!
