Will GM 200r4 work with factory floor shift location?

I just found the add on's to this thread tonight. Interesting about the governor and the speedo gears. I wonder how far mine will be off with the 3.91's. The builder said mine should shift at 5400 to 5800 rpm with the governor he installed at wide open throttle. Otherwise it will shift like a normal trans with light throttle pressure. Also on my lock-up converter, it only engages in 4th and automatically turns off if you forget to flip the 12 volt switch and slow down enough for it to drop into 3rd or lower. It's all internally hydraulically controlled, and only uses one 12v wire to engage/disengage the lock-up clutches in 4th. I wonder how that will work with a 3000 stall converter. It has 3 discs, so the added weight of a lock-up converter is not desirable if you are planning on doing a lot of 1/4 or 1/8 mile drag racing.I used an extension for my speedometer cable, which I think I saw on your post Treblig. It fits great.

JBC, I wondered about all that stuff a lot when I was planning my swap. To solve the problem I went with the non-lockup converter. I didn't know and wasn't sure when the trans would try and shift into 4th gear because it would probably depend on rear end gear ratio and tire size. And since I wasn't sure what gear ratio I was going to be happy with I couldn't take the chance. If your converter doesn't lock up until 3000 RPM your not going to be able to take full advantage of the overdrive. I'm running 3.73 right now with 26.5 tall tires and my RPM is around 2300 at 60 MPH (in forth gear). Using my car as an example, if I had your converter, it would never stop slipping unless I drove 80-90 miles an hour (or whatever MPH you get when you go 3000 RPM). My converter locks at 1800 RPM so at 60 MPH (2300 RPM) I know it's locked in. With your lock up switch you can lock your converter anytime but your stall speed will keep the converter slipping until you reach 3000 RPM. This creates some extra heat when cruising but your extra cooler should take care of that (I think). Even with a stall of 1800 like mine I worried about heat at lower speed (35-55 MPH) and that's why I installed a trans temp heat gage. As it turned out the tranny stays real cool at all speeds but my converter doesn't slip as much as your does??
I recently got some bigger rims 15 X 12 and even taller tires (29 inch). This will put me at an even lower RPM at cruising speeds so that makes me really glad that I went with a 1800 stall non-lock up converter. I might have to go with a lower gear but I still wouldn't have to worry about any high stall.
Hope this helps.....
