<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: 83hurstguy</div><div class="ubbcode-body">The challenge of the roller cam in an Olds is the 5/16&quot; rocker arm bolts. There are two basic options... the first is drilling the expensive/rare heads for a 3/8&quot; or 7/16&quot; stud and adding guide plates. Option 2 is the Harland Sharp 5/16&quot; bolt-on mini-shaft rockers, which are around $450, and good to 350 lbs open spring pressure.

With roller rockers, you'll have to modify/remove the stock valve cover baffles or double up gaskets. Ram Air Restoration makes a 0.200&quot; thick hard rubber gasket that's a nice piece. The stud mount rockers may clear with a short poly lock, but the mini-shaft ones hit the baffles at max. valve lift... went through figuring that out on my old '83 the hard way.

No doubt a roller is the way to go, other than those pesky Pure Stock rules. I'm stuck with the flat tappet for mine. </div></div>

thanks for the info..speaking with the builder...stay tuned... [img]<<GRAEMLIN_URL>>/smile.gif[/img]

Dave, you must have bought those a while ago as I've heard from more than one person Diamond quality control has really gone down hill lately.
I'd suggest CP's and BTR in NY has a nice deal.

Works for small blocks?

As far as I have researched this should be true:-) I want one!!

Albert's carb before/after:



















We were originally hoping to do a basic rebuild, but when I found the self-tapping inlet fitting (with no filter) and the corrosion &amp; debris inside the bowl (4th and 5th pics) it became a restoration since the bowl would have to be media blasted to address the corrosion.

Just another day on the job.

Thanks again Albert for letting me be a part of your build.
