Will GM 200r4 work with factory floor shift location?

After installing the new governor I cleaned the pan which had a little break-in sludge on the bottom. Then I installed transmission temp sending unit. After that I installed the pan and ran the wiring from the sending unit up into the engine bay. I filled the tranny with fluid and drove it home. Before the governor change the transmission would shift at 2000-2100 during WOT from a dead stop ( I checked it numerous times, it was very consistent). On the way home I made numerous WOT starts from a dead stop and the transmission consistently shifted at 2800. I was shooting for 3500-4000 but 2800 was much better than 2000. Now that I have another "standard" governor (the one I removed today) I can modify it by removing more metal than I removed from the one I just installed. I already have a good idea of how much to remove. The next time I drop the pan it will go much faster because I won't need to replace the speedo gears. OH!!! One more thing...I plan to get the 3.73 gears installed next week. After the new rear gears are installed I plan to make more WOT starts to see how the low gears affect the governor response, then I'll decide how much to remove off of the "standard" governor. It should be interesting to see how the lower gears effect the governor weights because the plastic governor gears run directly off of the trans output shaft. With lower gears the output shaft will spin much faster at the same highway speed than it did with the higher gears. The new plastic speedo gears should give me the correct speedometer reading at all speeds as they are matched to the 3.73s. I really enjoyed the ride home, it was nice to hear the engine wind a little without having to manually shift the transmission. I will update this post as soon as I make some test runs with the new rear gears.

PS- I have searched the internet for months and have yet to find a definitive answer to the question, "how does each governor weight effect WOT shifts, does the light weight control anything different than the heavy weight or do they both effect WOT shifts???" I removed some metal off of both weights but I have no idea which one helped?????
