Re: Newbe need help with cam slection

[Gary Pavlovich <glpavlovich@xxxxxxx>]

#4452759 is the grind I would select but make sure your cam is a hydraulic 
cam.

This grind is similar to the 340 cam and will provide plenty of HP/Torque 
with room to grow should you desire it later.

I would suggest a 3.23 Sure Grip third member, headers, and a slight 
increase on the stall convertor (if auto equipped) as an option if you have 
to take the engine out for any work.
