My car is actually faster off the line and out of the hole with a taller 1st gear and taller rear gear ratio such as 3.31 or 3.08. Have run a few side by side comparisons and at the drag strip. I can take off in 4th gear from a dead start with my FE and 3.31s. Same with my last Cobra FE with 3.08s. As for the TKO in a Big Block Cobra, I think as long as you get a TKO 600 or custom built one with out such a low 1st gear it would be fine. Most complain its a waste and start out in 2nd if they need to get off the line quicker with less tire spin.
As for "notchy" I too noticed the TKO 600s loosen up with some time on them but nothing close to the butter shifting TL, even with mods.
You are correct. I have a .030 over '27 with a '28 crank. Makes tons of torque. The top loader is a WR. I have started many times in 3rd. gear by mistake without a problem.
