This engine has shims...and needs them as well. I took it apart and am re-using and making more since having the crank turned .010. As the federal-mogul versions shims only come in .010. The OEM shim kits have a stack of .002" (3x per side) of each cap. But from what I can find, they type of kit isn't available.
I'm using .004 to .006" total pretty much across the board on each main, using a micrometer to master off the crank, & a bore gage to check the clearance on the mains torqued to specs. I'm switching to hardened ARP .120" thick washers. With bolts torqued to 100lbs, I can't see them backing off without lock washers. Worst case, a dab of lock-tight. Which I've never used on mains before.
I believe mid-55 to 56 is where the cutoff is for not needing shims anymore going from pin style bearings retainers, to standard style bearing retainers . I've researched this quite a bit and the machine shop who did the machine work was very familiar with them 235's as well.
As far as bolts being original, IDK. Currently, don't have anything to compare them too. The 216 is still in the truck. Thats the only reference I have access too. Devestechnet.com has been very helpful and I have his books along with factory service manuals.
Thanks for all the help and advice.
