Difference between 3:55 and 3:23 gears

-
Hmmmmm, I've never seen smaller than 2.45s so, 2.23s would truly be lame. lol

My HC360 FormulaS with a 223* cam, a Holley600, and double O/D,came to 1.97 final drive.That's 3.55(diff) x .71(A833) x .78(GearVendor) = 1.966.That makes 85mph@2076 rpm,and 65@1588. Nice Interstate cruising, oh yeah.
 
To get a mental picture, look at a yardstick. 29.4 inches, 32.3 inches 35.5 inches - you get the idea. An old timer showed me that many moons ago when I was trying to wrap my head around gear ratios on paper. You can always tape a ruler on the end for the big gears!
 
1988 5th Avenue came stock with the 3spd tourquflite and 2.22/2,23 7.25.

Even with the stock 120-140hp 318, above 75mph is where you can really feel the power.

Too bad you lose power at about 80mph! LMAO
