Thread: Help with Intake Manifold and rocker arms

It doesn't have to do with the cam, it's a suggestion for the ignition. Have your distributor curved so that the centrifugal ignition curve gives a nice, even spark lead of 22 degrees over the span of 3,200 rpm's. Using an initial spark lead or ignition advance of 12 degrees at the crank and 22 degrees in the distributor will add up to 34 degrees total advance at 3,200 rpm's. You may find a little extra power playing with it a few degrees either way on the advance at the crank. I'd use an adjustable vacuum advance module from one of the aftermarket manufacturers and play with it to maximize fuel mileage at cruise. If this still is unclear to you, hunt down either or both of these books and study a little on ignition systems.....

While I am a mere hobbyist, there are members on this board who do this professionally. May God have mercy on their souls

Rob, you don't need to feel sheepish about asking questions, all of us had someone who helped us learn this silly hobby and pointed us in the right direction.
