    Since there's some talk about this again I'm going to create a new thread.

    Back in 2005 FEOA member 'dada' had a prototype roller rocker made by Harland Sharp. Here's the thread.

    https://www.feoa.net/modules.php?nam...tdays=0&postorder=asc&highlight=roller rocker

    Here's the pictures 'dada' posted of the prototype.

    https://www.feoa.net/modules.php?name=Coppermine&file=displayimage&album=toprated&cat=13386&pos=0

    Jeff at Harland Sharp at the time was in charge of all the custom work and was a very busy guy. I phoned and left messages endlessly. After finally talking to him he told me that before a production run could be done the prototype needed to be tested and measured. There was an issue related to the rocker ratio I think. A that's were it ended. I lost touch with 'dada' a few years back so I don't know what happened to the single prototype and the testing.

    To this day I would still like a set but because I have so many other things that need to be done I haven't followed it up. Since there was some interest again maybe we should find out what happened. At the time the price was high ($400) because there wasn't enough interest to create a large order. If I remember right Jeff could go as low as $275 at the time if enough orders were placed.

    How many people would interested?

    At this point I'm not interested in running a group buy because it's not an easy task. I would however make calls, do some research and maybe get more CVH owners involved. Feel free to speak up.

    UPADTE - March 26, 2009 - Page 13
    One set has now ran over 400 miles.

    UPDATE - July 15, 2009 - Page 15
    One set has now ran over 7000 miles!! I've also been told that 5 sets are out there.

    Ordering Information
    If you want a set you need to contact Mike Becker at Harland Sharp. These rockers are not in their standard product line, they come through the custom parts department. As of July 15th, 2009 the costs are as the following. 1 set $327USD but if you order 3 or more sets the price falls to $280USD. If you want a set I suggest try getting three people together or post in this thread and see if anyone else is wanting to order a set. Here's the contact number 440-238-3260.

    I would be all over this in an instant. I would prefer aluminum ones, such as were produced before.

    Do they have needle bearing pivots also?

    Hah! I posted in that topic...one of my first. I'm still a fan of steel, only due to aluminum never having a safe stress point. Flex steel within 90% of its stress limit and it'll last nearly forever (literally). Flex aluminum once and it might snap the next time....not reliable enough for me. As stated in that ooooooold post, I want something overwhelmingly tough and rigid. Weight isn't a big deal in that department for me since we're not revving to 10k rpm.

    Pivot bearings and roller tips are a must for me. The rockers in that picture, though, are most apt to fatigue and crack at the bottom of the pivot bearing hole if aluminum is used.

    I'm going to try to track down 'dada'. I have some of his old email at home. I'll also contact Jeff again at Harland Sharp.

    If I remember the reason why aluminum was used was because the rocker blanks are cast. I think it was to expensive to start with a block of aluminum and start machining away. A cast blank is made close to the final shape then it machined to it's final dimensions.

    I would guess that Harland Sharp would have some type of warranty.

    I talked to a couple UK guys this morning if anyone over there had ever made roller rockers. As far as they know only one company ever did but they stopped selling them in the late 90's. One guy did tell me that they had a thread just like ours were once a year some asks 'what up with these custom roller rockers'. That made me laugh.

    machined aluminum is much stronger than cast...but like cow said, as long as they are strong enough, and we are not reving to honda like RPMs, steel would be fine for me too.

    Since I am going to be diving into the head sooner than later, I would be very interested in a set. The lower the cost the better. Now after reading the thread, the question was asked if it would work on the LX (CFI) too. Will they? I was planning on swapping to the GT cam.

    All years and sizes of the CVH use the same rockers as far as I know. The only difference is the shimming underneath for roller lifters, and the switch to mounting bolts, instead of studs.

    I just trust steel more than aluminum. If you've ever seen an engine die due to an aluminum rocker, you'd understand why I say that. I'm not worried about the mass as much as the stress.

    Has this been posted in the 2g and 3g forum, possibly the group buy section as well?

    Knowing how little the different generation people talk on here, or visit other generation threads, I doubt it. But it would benefit any year, so it might as well.

    If this will work on the other gens...I take it these would work on the SPI motor. If so I can post up the info on Focaljet. May have some interest there.

    Sent 'dada' an email last night. It didn't bounce so the email address still exists which is a good start. I'll give him a couple of days to respond before a contact Jeff at Harland Sharp. It would be better if we could find 'dada' because it looks like he might have placed an order with Jeff.

    I went over my old emails from late '05 and early '06. At the time 'dada' had only purchased the single prototype you saw pictured. After several email between him and me he decided that he would just go ahead an order a set. That was in late '05. After that I lost touch with 'dada' because of my inability to contact Jeff at Harland Sharp.

    I've also made a phone call the a another roller rocker manufacture to get some information about what he would needs to produce a run of rockers. I didn't ask prices because I'm not ready to pull the plug on Harland Sharp. We need to see if we can contact 'dada'.

    100% guaranteed to work on other gen CVH engines, SPI included.

    Ok, no response from 'dada'.

    Next step is Harland Sharp.

    I don't know if they'll work, but I'm sure you can check it out if it interests you. Rogue Performance Roller rockers, they are a Crane unit, aluminum, and 1.73:1 ratio. They were re-engineered for use on the vulcan powered Rangers, and we at the Taurus club have also used them on our vulcan powered Tauruses. They are basically 5.0L roller rockers. Again, not sure if they'll work, but hey who knows. LINK


    OR

    Tom Morana Racing, they have also 3 different ratio rockers. LINK

    Some what good news.

    I talked with Harland Sharp this morning. The guy that does the custom work is willing to produce roller rockers for the CVH. What he doesn't know at this point is how far the prototypes got. He took over the custom work a few years ago so he's going to call me back once he knows were things got to.

    More to come.
