    I haven't used them, but I would think if you were going to go to a roller rocker for stbility you would want the stability that a full shaft would have. The individual cylinder set up might tend to twist.

    They are less than the factory arm ratio. But why bother making them less than factory ratio?
    I agree with the Kid, high lift and strong springs is going to want to twist this around or deflect.

    My confidence level on these are low, if they do not even say what kind of aluminum they are made of, what the shaft is made of, maximum spring tension you can use, or have detailed instructions on how to install, torque, or set lifter lash.
    How do the bearings or wearing parts get any oil? It surely does not look like they considered oiling in the design.

    They might work better than the originals, but that is not hard to do. They are pretty though.

    www.speedmaster79.com is the company website.

    No mention on where or what they are made from.

    Good point on the rocker arm ratio! No idea why i didn't notice it.
    You'll have to agree dough, The pricing makes it work considering them. It's a shame that there are some set's sold but no-one ever wrote a review or about issues they might have.

    I've thrown them an email asking some questions regarding the product. If they supply any useful information i'll let you know!

    I have a barely used backup set of T&D 1.70s with one new style T&D replacement rocker (almost unnoticeable) and all hardware that I would let go for that money. We’ll over $1000 new. Anyone can PM me if interested.

    5One9 I am interested in your barely used set of T&D 1.70 rockers. What is the total cost including shipping to me at 95608. I assume these are ment for any cast Iron 472-500 CAD head. My heads are 950 small chamber cast iron heads.

    Ha, PJ,
    EBay's description ( same as the one here if you use it enough)
    is in English ( in German in the OP's post ) , just found out they are made in Australia by CNC machines and shipped from that Speedmaster79 site here.

    If you read on about a lot of speedmaster parts, they describe them as being made for them in a ISO certified manufacturing facility ’overseas’ (China is overseas from Australia too).

    YouTube a video called ‘500 Cadillac’ by psycho bob’s garage. He’s trying to figure out how to keep them straight on the head by using the original sheet metal retainers.

    I need to check but those rockers might be the ones that a friend here in Utah used on a recent Cadillac build.
    If they are the same ones he came up with a simple "fix" that keeps them from moving. I'll give him a call. He has pictures … (and so do I if they can be found).
