I picked up my 400 block from the machine shop in Vancouver, WA this afternoon, they put lifter bushings in it with .060 holes in them ,according to them
It is to late to unload it tonight due to cold, ice in the drive way and my old cautious age
I'll unload it tomorrow morning and get it into the assembly room and take a good hard look at it after cleaning it thoroughly and putting it on a engine stand, again.
Hopefully the low oil pressure issue is gone and it lubricates through the pushrods properly with better oil pressure
More info on this later when I'm done
