I have a set of bare W5's and am wondering what my current options are for rocker gear. I would like a durable setup, as I'm building the engine for street use and auto-x, with once or twice per year drag racing thrown in for fun.

Erson's would be my choice. I've had them and HS's. Ersons'simply have more material at the arch adjacent the spring, as a result of a smaller shaft. But they may be impossible to find. T&D would be my choice if big pressures are expected.


Damn! I dropped my change.............

I guess I should have bought a set of Ersons two years ago when I first heard about them. They aren't listed in the PBM-Erson catalog anymore.

I keep hearing about Norris rockers, but I can't find any info, or even if they are still available.

Get Harland Sharps and don't worry about it. There was a design problem with the Erson's, they're no longer made and therefore spares are non-existent unless you find someone with a broken set. The Harlands will hold up to anything it sounds like you will throw at them.

....care to explain?

We run the Ersons on my dads W5's. I think when I finally got ahold of the "powers that be" that they only had two sets left. In hindsite I should have bought them both. We've had no issues with them so far.

So, what was Erson's design problem?

The problem may have been only with the very early units. If I remember correctly the fix to the problem was to saw through one side of the hold down. I can't remember what the sympton was to require this mod. It's been a bunch of years ago. I didn't get to use mine because of lack of pv clearance(machine shop calc goof) so I sold them and went to the Harland Sharpes. They were very nice rockers and it upset me that I could not use them.

Do yourself a favor and buy Harland Sharp, T&D or Jesel. We had failures in two 1.6 Ersons and couldn't get replacements so I had to sell them as a partial set and buy the HS's for $1000.

Go with a company that has been in business for many years and will likely survive in this economy.

Jesel lists them for use with 48* lifter angles... but they seem to be much more $ than the T&D or Harland Sharps. I'm leaning towards the T&D.

I just got a set of W5s with the TD rocker setup - it is a very sweet setup and appears very durable. Each pair of valves has its own shaft and rockers so if you did have a failure you could replace just one rocker set.
Don't forget to plug the oil hole - neerly missed it -whew.
i can send pics if you like - send me a pm.
