Works for small blocks?

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

For changing out that illegal &quot;Pure Stock&quot; cam [img]<<GRAEMLIN_URL>>/dunno.gif[/img] [img]<<GRAEMLIN_URL>>/grin.gif[/img]

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.

Luke is a wealth of Oldsmobile knowledge:-) (I think he looked over this car at MCACN before it sold to Albert....)

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

All Olds timing covers are the same from '64-up, so it should work.

Thanks for the kind words, but I'm no guru. At the rate you're going, you'll have more Olds experience than me in another week or two. I did spend some time at MCACN sitting next to this Olds in the post car display.
