I’m just going on my experience. My 2110 was built by CB and dynoed at 150 hp. It was new with only a few hundred miles when the transaxle went out. I had paid for a 3.88 “freeway flyer “ so that is what I thought was in it. I noticed the car had a ton of power but above 60 it was revving higher than I liked so when the transaxle came out I talked it over with the builder and ordered a 3.44. I can’t remember exactly what we put in but the final drive equaled 3.06. It was just too much. When it came apart, we found a junk trans with 4.12s in it. That’s why I went so far the other way, I thought it was a 3.88. Like I said I lost some performance which I figured would happen but what I didn’t like was when I put it in 4th even slightly below 2,000 rpm It felt like it was vibrating or lugging. It might have been that I’m used to my other 2 cars that have 7 liters and 4 speeds and should have been running it out farther.
Anyway, the combination was geared too high for what I needed. I should have included in my post my too high 4th gear. Al B and I talked it over quite a lot before I bought the gears and I can’t remember why I went that high. Now I think the 3.44 with a 1.00 4th would have been perfect. I think this is the same as the 3.88 with .89 4th. I think the OP would be best advised to listen to Greg. He has built and driven a lot of these so he will know best. Thanks for your responses, you will never learn if you don’t pay attention to others ideas.
