marlinjackThe Machinist #5723 AMARGOSA MACHINE 'Running on Empty- Middle of Nowhere'

I went with "Comp Cams" "292" Degrees duration (advertized)and(symetrical)with .560" lift (also symetrical. Means The Intakes and Exhausts are exactly the same) Many recommend duration and lift that faver the exhausts. I have not installed it yet. I am still building the "4 Bolt" Cleveland. Yes! I faver the "underdog". It will be running 62.3CC (before polishing), Closed Chamber Heads with flat top pistons and one large valve relief. It looks like 10.0:1 to 10.5:1 Compression ratio "on paper", But remember that is "Static". I plan to bring it back down just a little, to 9.6:1 to 9.9:1, using the cam duration, thick head gasket, and polishing open the combustion chambers, etc. This cam Should have a pretty nice lope at idel, without being "hard to live with". Regards, Marlin.
