Fast intake and a BBK TB
I have a 80mm BBK hooked up to a 78MM FAST intake and it made 22 FWHP and 20 FPT over a stock ported TB and the LS6 intake at 5,000 rpm. This is on a 421 CI N/A engine.
At the time there were no 90 mm TB's so I just went with this set up for awhile.

Just go get 3 feet of 1/4 (I think) hose and a couple hose clamps. Run it from the radiator to the output bu the block. Easy cheap fix..

from my engine lol, but I don't see how they could have fit the BBK onto the FAST intake without the spacer that was provided by BBK.
