Driver may have a lot to do with it, but all things being equal, the car with 50-100 extra foot pounds of torque is the faster car.

Last I checked, CJM was working on a manifold that would really only be a benefit for the boosted guys. From his own thread, he didn't expect a huge jump in power on a NA motor. And GTM will never be a viable source for anything as long as Sam is running the show.

There's just not enough people who mod 370s to justify something like this from a R&D standpoint. There's not enough of a market for it to be a good use of resources as a vendor. Unless you jump in there yourself and figure it out as you go, you'll end up waiting a long time for someone to blaze a trail for you.
