Camshaft Blues

Included with the billet distributor was a book and a baggie with springs and bushings. I believe you will end up with using the largest (blue?) bushing and one light silver and one blue spring. That will give you 36° total timing (bushing is 18°), plus 18° initial timing. Second, there are two Edelbrock 750s. What is the list number of the one you have? One is meant for emissions and performance (#1407), and one is meant for performance (#1411). The 1407 will almost always have a lean spot because of the size of the passages in the fuel circuits. You can't change that. So if you have a 1407 I'd look for a better carb.. EIther the Edelbrock Thunder series or a Holley Street Avenger 570.
