    K11-410-8 - Comp Cams 'Magnum' Hydraulic Roller Camshafts is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Makes a BBC Sound Like a Sewing Machine Very disappointed in so many ways. For starters the "kit" did not come with the cam button retainer. Really a 3 dollar part that costs 45 cents to make couldn't be included in a 900 dollar kit? Then get it all together and number 1 lifter clacking like crazy, won't pump up. Read reviews find out comp lifters are garbage. 500 bucks for new set from comp, or $100 on china bay. Seriously considered china bay, but then I ordered 1 pair of comp lifters and sacrificed an afternoon doing the replacement. In the end #1 exhaust lifter was the culprit, got it all back together, fired it up and it runs great. Just sounds horrible. Sounds like solid lifters. Comp has a promo video that explains that anyone who installs a retro roller kit should be willing to live with "a little" noise for the sake of more power. BS. Why even use a hydraulic lifter then? I understand aggressive ramp angles generate more noise, but on a towing camshaft? Guess I have to order a chevy crate motor 454 if I want a quiet full roller valvetrain for my tow rig. Thanks for nothin Comp Cams.
