Intake Manifold
I was thinking of going with a F.A.S.T intake. However, I was told that the LS6 would do well too. Does the LS6 intake flow better than the LS2 intake?
Thanks

It just so happens that the LS2 intake is more restrictive than was originally thought so the swap can possibly show some nice gains on even an internally stock LS2 motor (this somewhat contradicts what I had stated earlier btw LOL).
Thanks
