    I need a new cam,lifters and springs mine are junk

    Should I go Solid or HYD. roller?????

    How much hp will I leave on the table with the Hyd.

    To turn an A in that range you need over 800 @ 6000 +/- depending on impeller. If this is an NA motor You'll need to do a solid roller.

    Why are you considering a hyd roller? You're looking at 625-650 hp at the impeller, measured HP. With a 540, that should be pretty easy.

    The only reason I was thinking Hyd. is ease of maintenance and the price of push rods. I run over a 1000 miles a season with a lot of WFO run's for 2/3 miles.

    I would like to make around 675 or better. It will be around a 10 to 1 motor.

    Sorry, just realized that while my impeller is an A, its more like a berk AA...You could probably accomplish your goal without a roller but the hydraulic roller would work well and save some of the maintenance of the solid.

    Either way, pressure fed pin oiling on the lifters, and a rev-kit. Extend the lifter life greatly.

    If that's your plan, I'd go with the SR. With a decent valve train you should be able to set your lash and be good to go for most of the season. Maybe run the valves once in the middle of the year. I think the cost of a set of pushrods is going to be less than the difference between hyd and solid rollers. HR's are getting pricy for a decent one like a Morel, and if you're going to be running WOT for extended periods, you don't want cheap HR's. I'd say even the good ones aren't your best bet for extended WOT runs, depending on RPM, of course. The ones you have are pretty beat up. A good SR would (should) last forever. I'd go for the lighter, more reliable valve train with more upper RPM stability, and be OK with maybe having to adjust the valves once a season. Other than that, the HR has no benefits.
    And I'm going to politely disagree with the rev kit.

    Check out the Isky EZ-roll solid lifters...these things work.

    http://www.iskycams.com/ISKY-RedZoneEZRoll3.pdf

    A set of these coupled with shaft mounted rockersis going to be near maitenance free..It seems anymore that once you get the lash set hot, it really doesn't move.

    Hey engine guru's >what caused the metal transfer lobe to roller?
    Could oil be a factor or weak spring pressure >roller hammering on the lobe?
    Soaker...those are Morel rollers, correct?

    Hammerdown , don't have guru status but fwiw my .02 ....

    All of the things you listed could be contributing factors , excessive lash could be another . A rev-kit on a solid roller keeps the roller in contact with the lobe so that it doesn't skip and skid when on the base circle and into the opening ramp of the lobe which will help it to live a happier life .

    Yes they are Morel HR lifters .

    The bad part is that they dont rebuild them anymore.
    One more reason to go Solid roller they do rebuild them.


    Thanks cjordon I will be checking in to the Isky as well
    Anyone have any feed back on them???

    Chris has an Idea on the cam that we are checking in to.

    SS , what rpm were you running with your old cam and lifters in the picture ? strange to see hyd. rollers fatigued like that , something wasn't happy there , maybe they were gettin some float happening . Best thing is probably to get a complete kit from who ever you decide to get the cam from , so that everything is designed , matched to work @ the rpm you want to run at
