Give that 6 some Cylinder Head! LOL Very Nice Results thats about 50+hp on the engine dyno which I would consider a Huge Gain!
I made a little over 440 with the 75mm Truck intake on my 11.3:1 383 iron LS But am now Stepping up to better everything and i can't wait to see what she does, I'm Going for anything over 475rwhp NA which in a Vette M6 would be over 500rwhp, we'll see!

The FAST car intake shows absolutely no gains over the LS3 intake time and again. Many people have posted their frustration after the swap. Magazines have seen no gains with the LS3 FAST as well. However, the L92 truck intake has shown a small gain over the oe LS3 intake from both Comp Cams and Mast Motorsports. I am curious why the recommendation of the car intake. Factor in the cost of the Fast intake, fuel rails, fuel lines, and new accessory drive and even if there was a minimal gain it would be quite spendy. I think the reason Fast hasn't released a square port truck intake is because they cant beat the factory one. I wouldn't be surprised down the road if they released one just to shamelessly get some sales. But don't be surprised when they show no gain. They're only giving you guys what you ask for.
