Here is what I am dealing with. 400 block, billet splayed caps so it has been line bored/honed. Last block Whitmore ever did so you know the work is good.
He just fuzzed the block, cut more on the cap side.
The front main you can still make out some of the factory machine work. Some of the mains farther back the factory marks are completely gone.
So I have a .010 under Cloyes set, "Z" chain so its the good German chain. Its not even close to fitting. I do not believe a .005 under chain would fit but have not tried one.
I think there are .004 under chains from Spots available.
First chain is a slightly used roller of unknown origin.
Next chain is a new Rollermaster and it is loser.
Next chain is Cloyed stock type and its a bit better. A 20 $ chain.
