Mike:
Regarding the 292 dyno tests: check out the Hi Performance threads on this forum to follow up on the great work tlowe and CNC-Dude (and many others) did planning for, and running the extensive 292 dyno tests. In due course, there will be a series of articles published in a major automotive magazine regarding the outcome of the tests. As I undestand it, there is apparently an article also planned for our 12-Port News publication and more extensive results will be showing up in this forum at some point as well.
There is a similar 250 dyno test currently in the works that presumabley will happen some time early in the new year. Many of us who contributed to the 292 effort will (or already have) chipped in for the 250 project and I'm sure Tom will appreciate any help you'd care to give.
