There are distinct advantages, especially for a street driven car that has the potential to accumulate a lot of miles. I firmly believe that the valve guide wear can be minimized with the adjustable roller setup. That is my main point in "one dimensional", the reasoning is not all hp related.
    ls1 rockers are rollers.
    mrr23, im not against rockers, what im against is the fact that most people who get rockers end up getting a higher lift cam in the future and the rockers have to go.
    also price wise rocker arm kit vs, cam kit isnt a huge difference.
    while the cam kit costs more, youll make way more power with a bumpstick.

    Only at the fulcrum, the end has no roller. On a full roller rocker of course the roller doesn't actually roll itself it slides, but there is a line contact that is more defined and is 90* from the rocker motion. The stockers don't necessarily wipe in this same well defined line. Next time you have yours off the car, just take a peak at the contact area, I think you will see what I am talking about

    then they should get a cam that will compliment the rockers.

    as far as pricewise goes, i'll never disagree that going the cam route will make more power versus going the rocker route for the money. but, people don't need to toss their rockers away just because they are getting a cam.

    this is what i have issues with. when someone asks about rockers, it's always the same two responses. throw them away if you have them, and cost. yes, they should know about cost and sometimes a piston to valve issues with some cams. but, at the same time, they should be made aware that you can have both.

    some people may not ever want a cam. they like the way the car idles, drives, and sounds. they just want a little more out of what they have now. and there's nothing wrong with that.

    hell, my wife is the perfect example. when i put the cam in her car, she no longer liked how it sounded. she doesn't like the rumpity sound that some cams make. and i only put a small 210/218 112LSA in it. she like the added power, but not the sound. she liked what the rockers did over the cam. more power, same stock sound. i just put her motor back to stock after tossing the #1 rod through both sides of the block and oil pan. she got upset that i took her shiny gold thingies off her motor. (not that you can see them) she was glad i took the cam out and put the stock one back in. (but damn it sounded good)

    That's what my wife called them, and then she promptly told Joe Vinci that she would need diamonds as compensation
