Is that a Kirk plate on the crank? I did mine with one. I installed it myself at work, but the machine shop I use for my big car stuff put it on their balancer just to see if it was close. It was spot on.
In case you haven't noticed, in my haste to get stuff cleaned up in anticipation of the governor arriving from Charlie earlier this week, I grabbed the wrong head and resurfaced it!! Found that out when I tried putting the head bolts in place!!
Oh well, I now have one for the K321 if I ever find a block for that project!
Will get it buttoned up today and painted hopefully. Supposed to be 540 degrees here yet today so I can quick wheel the table out of the shop and spray some black on it. Don't want to paint in the shop any more now I have it looking decent.
