You Know gents, if that 12 Port tech article was written by some Yahoo back yard mechanic, I would lean toward Panics assessment, but it was not. Pat Smith was technician of the year for many years and the crew chief for Dyson Racing. He is not just saying what might work, he is telling you what will work. Pay close attention to the type of 292 harmonic dampener you find, they are not all equal. The good one is hot bonded. A very good source of info on this is Tom Langdon @ Stovebolt. These are people with hands on experience, BTW, Tom was deeply involved with GM's advanced powerplant division. These are serious people with excellent advice to follow.
