Which rocker arm's are you guys going with? Preferably, i'd like to hear from anyone making over 600rwhp but all are welcome. This will be a 347/D1 combo. I was thinking of going with the Y/T's but just wanted to get some input.

Thanks in advance,
Chris

I haven't heard good things about the Y/T's. I had some, but was getting valve float. I ended up selling them and had my stock ones rebuilt by Harland Sharp with their bearings, and they installed these C-clips so if the rocker arm fails it wont fill your engine with all those needle bearings.
If you do want aftermarket roller rockers, there are much better alternatives out there than the Yella Terras.

Yeh, well this is why I posted. Trying to get some feedback on what I should go with. Thanks for the input man.

I run the stock ones combined with 918 springs, etc. Zero issues.

We use the stock rockers on most of our builds. Check out the project car section of my website, many ProCharger builds in there. Bob

Thanks for the help guys. I had been using the stocker's on my previous setup with the P1 but didnt know if they were worth replacing.

I use the stockers also with dual valve springs.

I use the the stock rockers/pushrods/lifters. I do take the valve covers off every once in a while and look at them, but I figure if they havent fallen apart in nine years they will hang together for a while..

We use stock rocker arms or Harland Sharpe upgraded stock rocker arms. Anything other than that we have had issues with.

The only way the YTs will cause valve float is if the springs are already on the edge. The YT rockers are heavier on the valve tip than the stockers. The new YTs are supposed to cure this. Ive never had a problem with valve float with my YTs even when I had a nasty H/C setup.

I have rev-ed my yts to 7000 routinely with no problems. That means nothing to the people that have had problems I realize. Will use them again soon as Im running again.
