Comp Cam Xtreme Energy .477/.480

For those who are looking for just a step above stock, but want to retain the stock torque converter, stock cylinder heads, etc, this cam is the way to go. It's also a great choice for towing, RV use, etc. With a nice broad power band of about 1600-5800 RPM, this cam will give your engine a "slightly rough idle," just enough so people can tell you've "got something under the hood," but it will do it without losing hardly any of the low end response and drivability of a factory high performance cam. Duration at .050" comes in at a nice docile 224 degrees on the intake and 230 on the exhaust, and it's on a 110 degree lobe separation angle. We would NOT recommend this cam for any of our larger (500CI+) stroker setups, it's going to be way too small. 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 uses a single spring, but requires 10 Degree locks and retainers. Use our 145-1002 locks (with 11/32" valves), and our 145-1003 retainers.
