Russ, many of these issues are being addressed currently. This exercise will yield several benefits as an objective. It began as a before and after test for the "lump" head to reveal the gains possible by doing this modification to the Chevy 6's, first with a stock type head with the usual mods people would try to do to these heads if they didn't know what a "lump" head was or were uneducated about how to modify the 6's, then bolt on an equivalent head that had the same mods done to it, but with "lumps" also added to show the huge gain from them over the previous head, now it has blossomed into a dyno session with an assortment of parts swapped. I know its hard to believe, but there are many thousands of hot rodders outside the world of Inliners that have never heard of Leo or his book. So, this will help enthusiasts become more familiar with these engines and how to modify them, and hopefully fuel the interest in them and lead to more interest in them as well. It will also help show some hot street combinations for others to duplicate, with real world data and feedback. All of this will be featured in a "top shelf" national car magazine in the coming issues. So, any details that might be missed here, will be revealed in the magazine article. I am writing the article, and have been working closely with Tom in the past months on some ideas in this area, and it has just grown into the project you see now, but dont think this is just a spur of the moment idea, we have been building up to this point for a while. So stay tuned, it will be both informative and educational to those who have always wanted to see what parts are the most beneficial and practical to use on your 6's for a good street combo.
