I was just reading a price and flow comparison of the major head manufacturers, and Edelbrock pretty much has the best deal going, and if (like me) you factor in the other important matters, like customer service, hot rod community support, "Made in America" keeping our neighbors in SoCal employed, and their annual "Revved up for Kids" charity car show for the kids at the Center for Learning Unlimited ... well, see if you get that package from their competitors like Indy Cyl heads, factory hi perf, Holley, AFR, Trick Flow, Brodix, Dart, etc etc. Plus, I dig the family history and involvement in hot rodding from the 1940's from Vic to Vic Jr. .. and that 1969 1/2 Four Fourty six pack super bee test mule! http://justacarguy.blogspot.com/2011/05/vics-garage-collection-of-edelbrock.html
