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.
