Response to Yes sir. highway gears can be intoxicating.

All depends on what you want most from your car. Around 1984or so, Car Craft was hosting a "Street Machine Nationals West", in Clark County Washington, just North of Portland Oregon. I wanted to attend with my R code 428 CJ 4 speed 70 Mach 1, but knew the 300 miles each way (all I-5 freeway) would seem twice as long with the 4.30 gears. So I threw in a 31 spline 3.00 3rd member I had laying around, and put my L60-15 Pro Tracs on Magnum 500 wheels on the fold down back seat, and swapped on a pair of tall L78-15s on the rear. Made the freeway trip much more relaxing, but once I got there, ans put the L60s back on, I was absolutely shocked at how much performance the car lost with the "highway gears". It was embarassing. They had drag racing at Portland International Raceway, something I would have normally been gung ho to do, but I was afraid of embarrassing myself! The Mustang ran mid 12s with the 4.30s, but with the close ratio toploaders 2.32 1rst gear, it felt like it would have had a hard time running in the 14s, so I watched all the other guys having fun. Once I got back home, I couldn`t get those 3.00s out of there fast enough!! Afterwards I did a couple of 150mile (each way) treks to race at Seattle & Bremerton dragstrips, with the 4.30s buzzing the 428 about 3500 RPM, but no way in hell were the 3.00 ever going back in!
