wondering who all has a intake manifold swap other than the F.A.S.T. and what gains you noticed? dyno printouts??, just pondering the idea of doing a swap and saw a "Typhoon" intake manifold on ebay and thought i'd look nice under the hood, also is there any way with the stock plastic ls6 intake to mount the engine cover back on to retain the "facorty" appearance?? maybe use a plastic welder to melt the peice the bolt screws back on to the ls6 intake???
