WOW! What rpm were you turning while cruising 75 mph with 4.56 gears and a 28” tire? 5000? I have 3.91 with 28” tires and turn 3000 at 60mph. That thing must have been singing!
I put 4:56s in my 68 Coronet 383 4 spd car., back in the early 90s. Put it on 275 ONCE.. open headers, lasted about a week..... car Was sick w/ them! But She Ran like a Scalded dog, w/ 3:55. Miss my Baby Still!
