Once again trying to sort out issues with Sparky's 63. So we got the 327 broken in, and a rough tune (still sorting that out). But he is not getting the 2-3 Upshift till about 50 mph. Here is the info, 327 with circle track cam pulling maybe 11 inches of vacuum (at least currently). Modulator is hooked up, and checked with a vacuum pump to make sure it does hold vacuum. It was adjusted and made a little difference with the 1-2, but not really the 2-3. Today he pulled the governor, I had a calibration kit so we popped in 1 heavier weight, but that didn't change anything that he noticed. 3.08 gears at the moment (3.73 soon) th350 out of we don't know what, it came with the car and has never ran that we are aware of. He is running a 3500 stall due to the cam. Do we change out the other weight in the governor, or are we headed in the wrong direction? Also I did disconnect the kick down cable just to ensure that was not causing the issue. Any ideas or suggestions would be appreciated.
