I did ask you Rod and you said you already had one. The girdles are pretty much all the same, I just made them work better.

A 1/2 fill works good on the street, to the top of the freeze plugs. Keep an eye on the oil temp, and if it becomes an issue just run an oil coller.

Ya,,,I have an alzheimers issue myself,,,lol. I have pretty much ordered and replaced everything on my car in the last 6 months and my head is mostly filled with a jumble of parts etc. Keeping it all straight at times is an issue.
I was hoping you'd chime in again Mike. What exactly do you use to fill with? And is there anything you need to do to prep the water jackets, shotpeened like someone previously mentioned? Thanks
