This past weekend, 60s were all over the place, generally 1.30-131 range. I usually go 1.25 or so, depending on track. Mph was down also. Used to, I could only hold car on footbrake car to about 3200 and I had to stand on brakes. This time, I could easily go to 3500, and still only 60 1.30. Trans fluid is full, looks pretty good (usually looks new). Gonna bite the bullet here at the end of the year and swap in a 1.80 straight cut glide with brake. sticking a new converter in till mine gets back from repairs. Wondering if it will improve, or slow down. Specs: 2780 lbs, usuall in this weather it will 60, 1.23-1.25, run around 5.9s @114mph. 92 fox, 2780, 6.0 aluminum block ls, 950 gas carb turbo 350 with 5500 8 inch converter, 4.10 gear. swapping to glide with 1.80 straight cuts and pro brake. 5500 8inch converter suppose to flash about 6200. The new converter is aggressive hit, my current stall is a soft hit. Wondering if I am going to like the switch.
