What were the lowest and highest gears Pontiac ever put behind its traditional engines?

My guess is 2.41 and 4.33.

Am I right?

The Tremec TKO600 with a 3.55 gear mimics a Muncie/4.63 gear combo in first.

The Tremec with a 3.55 gear mimics a Muncie/2.27 gear combo in overdrive.

Both higher and lower than anything Pontiac put in.

3.73 Gear with the Tremec would be like a 4.86 and a 2.38 rear gear in first and overdrive.

4.10 Gear with the Tremec would be like a 5.34 and a 2.62 rear gear in first and overdrive. (but one might start running out of rpm at the end of the track?)

4.33 Gear with the Tremec would be like a 5.64 and a 2.77 rear gear in first and overdrive.

4.56 Gear with the Tremec would be like a 5.94 and a 2.91 rear gear in first and overdrive.

Hard to believe you won't run out of rpm in the quarter mile with a 4.56 gear. Are you running a 455? Your car must be a lot of fun on the starting line!
