Torker II or M-1 Single Plane?

Jeff, the intake should be useing the old style water neck, which can also be purchased new from MoPar. It's also a bit thicker at the base.

The M-1 is better than the RPM (Air gap or not) in certain arenas. Race rides would benifit if the RPM band in which they operate in are higher than the RPM is built for and also while skipping the lower RPM band in which the RPM intake works great in.

At one some point, a single plane is better than a dual plane. Alot depends on driving as well as engine make up. (Combo)
The orginal poster wantrs to stay with a single plane intake. Thats the bottom line.
