I got the cuda fired on the weekend after the engine being out for almost a year. I had corrected a problem where the rockers were hitting the valve cover baffles slightly, and I thought that would correct some of my valve train noise. It didn't. I have a comp hydraulic roller camshaft and Crane Gold rockers. I am going to reset the adjustment, again, to try and quiet it down.
Now my question. All of the articles I read say to start at zero lash and tighten the adjuster 1/2 turn. They all seem to refer to Chevy style adjusting nuts. I am wondering if you need to turn the adjusters more on our style adjusters, to get the same preload. My theory is that because of the finer threads on the adjusters it may take more turns to depress the plunger the same amount. Also if the chevy style nut is pulling down in the center of the rocker is it depresing the plunger 1.5 times as much? (multiplied by the rocker arm ratio). I was thinking I should see how many turns it takes to bottom the plunger and adjust 1/2 that much so it is in the middle of it's travel.
