It's not necessary. You deal with the engine builder/dealer, and they are good and bad. Bob George is an Indy dealer and his integrity is absolutely beyond reproach. But, you call Flagle or Lazzari and all you will get is P.O.'d.

The fact is that their stuff is good...and guys run real fast with it. My advice is to find a good engine builder that has good relationships with them and let them handle it.
