That may not be totally true. I've been working with GM Goodwrench on this project for about 18 months now, and they've been VERY supportive. Can't give you any details on their actual support,but it has been VERY significant. All of this will be detailed in my article when it gets to the engine portion. Next issue of the magazine is going to feature brakes. However, I'm moving the engine article ahead of other mods now that the ECU log jam has been cleared. Should be in print by February. At this time you can by the 4.2 short block direct from GM & the head as a separte item.
