Comp Cam Xtreme Energy Hi-Lift .564

Our favorite Comp grind, the .564" lift Xtreme Energy Hi-Lift Hydraulic cam, is the one we've used most in our 500 or 512 stroker motors, and it never ceases to amaze us how much power this thing makes, and still idles like a kitten at 800 RPM! With relatively mild aluminum heads such as Edelbrock RPM's or our Stealth heads, in a 500 or 512 inch stroker, this cam almost always makes somewhere in the mid 500 horsepower range (540-560), and idles smoother (and is more drivable) than a typical "Mopar .509" cam would be in a non stroked 440. Most stroker engines will find a nice wide power band of about 2500-6500 with this cam. We'd use about a 3000-3200 stall, and some decent rear end gears (3.55-4.10 for the street.) With 251 degrees of duration at .050" on the intake and 257 on the exhaust, these are ground on a 110 degree lobe separation angle. For serious street strip cars (especially 500+ strokers), this cam has some awesome top end capability, and like we said above, the best part is that it does it without sacrificing idle quality and driveability. This baby is STRONGLY recommended. We can't tell you how many people have called us back and can't believe the results they've gotten using this cam with one of our 500+ stroker kits. We feel the three bolt timing chain attaching system is far superior to the single bolt, and so we offer this cam to fit only three bolt timing chain sets. We carry them (along with the required bolts, etc.) on our timing chains page. Don't forget to order Comp lifters and break-in lube (shown below) with your new cam! These items are considered essential to ensure that your cam has the longest possible life and is fully covered under Comp's warranty policy. And, since this is Comp we're talking about, you can be assured of two things: The product is 100% made in the USA, and the quality is second to none. This cam requires 10 Degree locks/retainers and double springs. Use our 145-1002 locks (with 11/32" valves), our 145-1003 retainers and our 145-1013 springs.
