Unless you like to run racing gas, you might want to be careful about increasing your LSA and reducing your duration if you are already running 9.5:1 static CR. What you are effectively doing if you go that direction is increasing your dynamic CR, which could lead to detonation problems with today's crummy gas. You might want to verify your actual CR before you decide on a cam. Were any of the combustion chambers CC'd to arrive at a true static CR? A part # for the head gasket would also be helpful to determine the thickness. No way to really know deck clearance without pulling a head, unless Tyler had this info recorded.

Was looking at a comp cam #11-236-4, 226/236 duration @.050 and 544/547 lift , LS 112. Called Edelbrock to check on the # Z010 that was on the cam, and they said that # was a small block cam? so I have no idea what was really in it. If you check the old cam with calipers it comes out around 510 lift.
