dual plane manifold required , rpm air gaps are my favorites. , wide lsa 112 adv.2 , mild stick about 244 @ 050" max.. going to bring lift down to reality at .596.". good for valve guide life etc.. on a hi miles streeter. .. kiinda like a marine camshaft thats got to have 11" or more vacum for the efi and shift delay on the drives to shift right at 800 RPm idle speed.
390$ for this cam. rpm range in your 500 "er .. about 2400 to 6200. shift by 6500. good spread of power at low rpms for the 6 spd.
