LS7 Intake Manifold Options Hi. Does anyone have any experience with any aftermarket LS7 intake manifolds? Who makes them? What are the aftermarket options? Any custom painting or porting available? Seen the Wilson manifold, out of my price range and not what I am looking for. Please advise.

I see why he is a restricted user. Anyway! Fast at the current time has no plans on making an aftermarket piece for the ls7 so looks like porting the stock one will be the best bet. Plenty of torque down low and wont fall on its face like the l76 up high.
