Is that correct.

FWIW I thought the last 800 came from the 80 T/A with the 301 turbo. 750 cfm after that.

Yes, 1 7/32" throttle bore for the 800, 1 3/32" for the 750.

Most all truck Q-jets were 800 cfm in the 80's. I have a Q-jet from an '83 Z28 that is officially rated at 795 for some reason, but it is a 800 cfm carb.
