Hey everyone, haven been on here in a long while. I am going to swap gears for the 3rd time in my 62 Impala and was hoping there are a few out there that has had experience with these combinations. I am running a 200r4 behind a sbc 350 with approx 350HP. I originally had the th350 and 308 gears, then went to the 200r4 and back to the original 3.36 gears and have never been happy with that combo, its pretty sluggish for my liking and I think my engine would like a few more rpms on the hwy. I am really stuck between the 3.73 and 4.11. Even with the 4.11's it doesn't look like the hwy rpms are out of line, just dont know about its in town manners. Any help would be greatly appreciated. This will be my 3rd swap and hopefully the last one.
