Ok, cam specs. Comp Cams part #60-000-5. CAUTION! My block is a 53 so it uses the small bearing journal cam. Don't order by part number unless yours is the same year. Later years use a larger journal cam. Also, mine is a hydaulic but I won't use a hydraulic cam in one of these motors again. The lifters available are junk! Mine clatters on cold startup because the lifters bleed out just sitting. I talked with Comp Cams tech dept last week and they ok'd installing solid lifters on this cam set at .008-.010" valve lash. I've done this before on a small block in a drag race car and we made it work perfectly.
Ok, cam specs, I got side tracked. Intake lift .463/Exhaust .469. Duration @ .006 lift: intake 261/exh 275. Lobe center: 110 (installed at 106 as recommended using offset crank key). I'm also using Comp Cams valve springs. Valve to piston clearance is tight so check things close.
This cam has a nice lopey idle and lots of low end power. We actually pulled 5000 rpm on the dyno but stopped making power at about 4600. I'm thinking the lifters were holding it back. My engine idles at about 550-600 rpm. It's amazing how many folks think it's a small block from the idle sound - that is until the exhaust barks during 2nd gear accelleration! lol
