I am very interested in your FiTech install. We have used the FiTech on a number of V8's including replacing the factory system on LS engines. I've been waiting for a customer to request one and figured we would have to get a 4bbl intake for a 235/261 and then use a four to two barrel adapter. Your 302 is already there. GMC's were often worked hard and were in the 10-12 mpg range and maybe 13 or 14 for an unloaded highway pickup so mileage with the FiTech will be of interest. Keep us posted!
