| With Comp's Hydraulic Roller Retrofit camshafts, you can get all the benefits of the increased power which comes from a roller cam with the low maintenance of a regular hydraulic. Plus, there's no worries of the cam going flat, having to do the correct "break in" process, etc. This is the biggest hydraulic roller Comp makes, and for most street/strip stroker motor applications, we've found it works great. In a 500"+ stroker, this cam will make power from about 2500-6500. The .549/.544" lift and 242 intake and 248 exhaust duration at .050" allows for nice low end power without giving up strong pulling up top. These are ground on a 110 degree lobe separation angle. We'd use about a 2500 stall, and some decent rear end gears (3.55-4.10 for the street.) With this setup, we recommend our 145-1008 Hydraulic roller lifters, our 200-1058 springs, our 145-1003 retainers, and our 145-1002 locks (if you are using valves with 11/32" stems.) Our 145-1006 titanium retainers can be substitued as an upgraded part if desired. Also, this cam uses 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. |
