A Quick TQ I.D.

Then it us 1969 model. I have had it apart and it has the press/o-ring jets. Does one measure the primary bores to determine cfm? I have wanted one of these for years and finally found this one a year ago. If it's the 850, I may not have much use for it. If it's "big bertha", it's going on my 700 horse gen 3.
