Default Re: 276 stroker from 35 years of parts

And I watch my oil pressure like a hawk. Ask my kids... On long driving vacations (every family car we owned had high mileage), my mood would revolve around the oil pressure I was seeing on the aftermarket gauge. Here are some photos from this morning's adventure in cam cleaning. I mic'd the heel/toe dimension before and after sanding with 600/800/1000/1200 wet dry with MMO for lubricant. This gave a surface I could live with for the lobes, The journals took a lot less work. I downshifted the lathe into back gear on the lowest of 4 belt speeds and was at 35 rpm. The journals remained constant at 1.795-1.796. But get this..... Using my dial indicator with cam in the lathe(not running) I found .341 gross lift on the ones I had not surfaced, and gross lift on the two I completed to my satisfaction I had a gross lift of .338 and .339. I knew my method would take more off the toe as the oak splint exerted the greatest spring pressure at that point. Must be why someone altered the EA designation. Anybody want this thing? Unfortunately the other 2 cams have similar sized journals. I already have gaskets, can I buy that nos 8rt cam?
