Re: 68 c20 step side
Welcome. Let's see it. You should show some respect for your Quadrajet. I don't know of any aftermarket carbs that are still around after 40 years. If you rebuild it you'll find it's hard to beat. For power "AND" economy. You will have 4.10 gears or lower

Re: 68 c20 step side
You can hope for 4:10 gears. Mine has 4.58's, and 5.38 aren't unheard of. Quick off the line though.
