For those that are not aware or have missed it, Street Rodder published another article on the history of the Nailhead. Incidently, I was interviewed, and spoke with them about my experience and results with my 425 build along with the hurdles of todays Nailhead builder. There is some interesting information here that I did not know, but it also plugs a few key individuals and resourses that have helped make the Nailhead famous again, Such as Russ Martin, Tom Telesco, J&C, TA Performmance etc... Be sure to read all 5 pages- a good read. http://streetrodder.automotive.com/93593/0811sr-vintage-buick-engines/index.html Erik Schmidt
