Interesting. That is good to know. I noticed that equal shims centered the crank better on the 2 and 3 bulkheads, but seemed worse on the ends and the time chain was out of alignment quite a bit, the crank gear would go to far back. The gear on the crank could be shimmed forward though to align it better.
That leads my to wonder how much that alignment matters within .030” if the thrust clearance is correct, the pistons have that much play up on the small end pretty easily. I think that single shim is something like .068” thick. Best I can recall anyway. Yours was likely .034” ish on both sides by the sound of it. I know I am not the only one that has done a single shim, but I have heard of guys talk about 2 shims too. Be interesting to see what this next crank and block combo likes. Maybe I will have to do 2 shims
