Re: Camshaft and Dist Values
What's the scoop on the 3904366 camshaft? Is it an old, original one? The reason I ask is, I am involved in Pure Stock racing, and I've been looking for a known *original* LS6/L72/L78 camshaft to run through the cam doctor and check the specs versus the current reproduction cams...so I might be interested? Any help is appreciated!

Re: Camshaft and Dist Values
With the clearance set at .024" .028" you get .496" on the intake and .492" on the exhaust. Over the years GM opened up the clearance specs from .020" .024" to the later .024" .028" This affected the power characteristics of the engine especially the bottom end torque output. Tight clearances would help in launching on poor traction tires.
