Default FAST manifold ?

I am going to put a 78mm FAST manifold on my truck. What is involved with making it 90mm? Is it just changing the top piece?

Yeah, you'll just have to buy the 90mm shell and change out the top piece. Then you'll need a 90mm TB too.

I think they figured out how to use a LS2 DBW TB on the trucks now, I wonder if I would see a nice gain on a stock cubed 6.0?
