I've thought about it before, and thought about what would be needed. I have done the swap in an older Camaro though.
I'd go with a setup from an LT1 car, and use the Camaro slave with the truck pedals and clutch master cylinder. That should get it close, fine tuning could be done by changing the clutch master attaching point on the pedal, making the rod adjustable, or trying a different master cylinder. You can use a driveshaft from a 700r4 equipped truck. The T56 is electric speedo only, so you would need an aftermarket speedo, or adapt a cluster from a '90-'91. I'm completely unsure of where the shifter would poke through the floor at, or how long the shifter would need to be.
One downside to the LT1 style T56 is the pull-type clutch, it's expensive. I bought a Zoom clutch and have been happy with it.
