Kinda surprised GM didn't do that.

On the joined runners, I *think* there might be a far bit gained since you
had the length but not the velocity of the uncut runners, on the cross fires
the runners were like 3x4" square, and still made good power,

The happiest people so far are the Supper Ram ones.
