This cam is used in our own shop SVO car and is capable of 600+rwhp.  It is a newer design with high velocity lobe profiles (properly timed) and is best suited for ported heads that can take advantage of it's high .585" valve lift.  It is a short duration, high lift camshaft that we feel is the ultimate street turbo cam for the 2.3 . It still retains very good low rpm power and idles near stock. We found it makes excellent power from 2600-6700RPM.  Valve springs with a minimum of 150# closed seat pressure are required. Will fit in stock heads with our engineered Beehive valve, spring and retainer kit- no machine work required to guides or spring pockets.
