This was with a 904/Proflite. I made the change in my V-6 car from a well prepared 1.98 PG and 7" converter combination. The first ratios I chose were not best for the 3 speed, but I didn't want to over do it and I used the same converter. 2.12/1.35
3185 lb car it picked up a little more than a tenth. Most of it because of the second gear (no fall back). I then went to a 2.45/145 and got another .08. Then I changed converters and picked up another nickel.
The first test was a back to back at the track. The converter change was at the track..so easy to change ratios and simple.
I'm sold on them.
I have several gear sets and am about to pull the trigger on a turbo 350 version.
