Looking for opinion on 3.55 gears in a 68 GTO with a four speed manual. Is that going to be a good all around gear for a daily driver? I understand the 3.55 gears were the norm for cars with the four speed, but of course 50 years ago, gas was cheap. I would like to have lower rpms at highway speed, less heat, less noise, better gas mileage. Are the 3.55 gears going to be a decent ratio?? Thanks in advance for your input!
