3:31, I'm cruising along about 60 mph on the freeway, and just for kicks, drop it into 2nd and nail it! Eh eh, love doing that 2nd gear thing at freeway speeds, takes off like a rocket!
Close ratio top loader, the gear ratios in the trans DO make a difference as to what you can and can't do as well as the rear end ratio.
Oh by the way, I got 11.5 mpg with my 427 and DUAL carbs on the last tank of gas. Steady cruising at about 2800 rpm, not bad! Heck my Jeep V8 does only slightly better!
