3B and Jimerit,Thanks for the info. I was told that car distributors and truck engine distributors are different. Is this true ? I thought they were the same. The people at summit racing was most helpful to me than pertronix. I would be interested in any further information on the pertronix ignitors. It's interesting that there are so many different applications.

Thanks again !!!
