Roller Camshaft Rpm Range

Always had good luck with 3310's. Put a lighter spring in them with a secondary block and run em.

Had Low 12's streeters run them. Do I prefer DP carbs... yep!

Just cause it will spin 6500 doesn't mean it will be faster shifting up there. I'd do the stagger step, 5800,6000, 6200, 6400 and if at a 1/4, leg it out the back wherever it traps. You'll find the sweet spot.
