twin srew or radix....

I'd go with the whipple, but only the 3.3L compressor. Those things(modified roots, twin screw) make heat and there is no way around it. With a larger compressor turning slower it generates less heat.
But for the package, there is no other choice IMO. - RADIX

do you have any data on this?

But if you think about turbos. Small ones spool quickly, but when pushed to their envelope they start to become ineffieient and produce a lot of heat. When you go to a larger unit at the same flow-boost levels it will produce less heat.
Kinda like the situation Parish is in. His engine is kind of large for that turbo from what I understand. Getting out of it's efficiency range. I'd wager that with something like a 88 on there at the same boost, he'd go faster, due to less heat. His tires seem to be the limitation at this point.
Maybe Blown can chime in.
I guess you shipped the splash guards today if the paypal went through.

Mr. Davis suggested a larger blower to produce less heat, as old GMC style lungs are usually installed without an intercooler.

Fandango is right ... bigger blower, less pressure per square inch on the blower, same psi in the intake, less heat. But ... now does that make less heat than an improved roots with an intercooler? Probably not. My vote still goes to the RADIX.
If we're shopping for an 8.1, that's a different animal since there isn't a RADIX kit currently available for an 8.1.
THe off idle torque is tire blowing strong. You see the cideo of mine in the General section? It was good for a 1.598 60' on ~7 1/2 psi.
