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.
Thanks for the info. I will pull it apart and see what I'm working with. I will use the oil pump this time around to confirm girdle alignment. Only other oddity to consider is the crank scraper. When the counter weights are "in" the teflon portion of the crank scraper, end play drops to .001". Obliviously this will change after the crank self clearances the teflon but it may be pushing the crank into the thrust bearing causing issues. Regardless, I'll pull it apart to be safe.

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!

Here's another quick update, installed the fitting for the LR steam vent kit in the cylinder head and got the head bolted on and torqued down. Progress!


Coming together!

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.

Thats with ARP studs? Are you still sneaking up on it in 3 steps? Thanks for the heads up!

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!

I'm not going to run the belt cover. I still need to figure out how to mark TDC on the crank pulley once it's installed though!
