What cam do you guys choose? I have the 440 do you guys prefer the "xtreme energy" cams for certain reasons or the "high energy" cams for other reasons. It's just for a stock 440, iron heads, maybe headers, 750 dp holley carb, auto trans, 3:55 gear, power brakes conversion kit. Whats the main difference in these cams? basicly lift . How do they trans late into power/performance/idle. Which one's are more street friendly. Thanks Jay

You might want to check out the Lunati "voodoo" series of cams too,i've had great results with them in 2 different motors

340srule, I have heard good things about those cams aswell. I'll check them out. Thanks for the info. Jay

the main difference between extreme energy and high energy cams is ramp speed and lift. with stock heads comp cams magnum replacement, #21-305-4, or the extreme xe268 would work fine. keep in mind that maximum lift should be .490 for safe retainer to guide clearance on stock heads.
