Jon, before you arrived to the seminar, Mike Eddy also spoke about the Individual Runner (IR), dual four barrel Holley (Dominator style) set-ups and off-set distributors used in the 1969-spec Boss 302 engines. And before that, Craig Conley spent a good bit of time reviewing the tunnel-port heads that were used in the 1968 season.
Only mentioning this in an effort to recognize the folks who loaned their time, effort, parts and knowledge.
Ross Myers and Chris Liebenberg also need to be thanked for bringing parts out from Pennsylvania for the talk.
On the ballistic gel coated bellhousing, Brian Ferrin was lucky enough to score that piece at a swap meet. He noted how you could still see the remnants of the "Sharpie" permanent ink with the price(s). He said that the first time around to see the part, it had $40 in permanent ink. The next time around it was $80... but he was able to talk the fellow down to a final purchase price of $50.
