Have any of you changed your manifold over to a Vette's manifold. I ask bc I don't want to buy a FAST intake that is $400 more.

 

which one are you talking about? If you're talking about the ls1 manifold then it's a waste of time. The truck one flows better. If you're talking about the ls6 manifold there have been a few people that did the swap but it's more of a conversion than a swap. Use the search button to see the write up someone recently did.
Manifolds in order of which is better.
LS1<Truck<LS2<LS6

 

Ls6 manifold but it should bolt right back up right?

 

here we go again...
