.480/230 cam in an 8.5 CR 360?
I just tore down a 360 I've had for 20+ years, zero to low-mile rebuild when I got it, and very little use since. The cam looks to be an older Lunati Bracket Master 2, (as all my timing events match), w/ .480" lift, 230 deg duration (@ .050), and a 109 LSA. As it's installed straight up, centerline is 109 deg, but Lunati's cam card says to install 2 deg advanced. It's got 1.88 J heads (70cc), Speed Pro/Sealed Power H405P pistons, and 8553 head gaskets, for a CR of 8.5-1. I've driven this thing so little, I don't really know how it acts. It's for a '65 Belvedere, 727 with a 2,000 +/- converter, and 3.23 rear... car will just be a pump gas driver. Is there anything to be gained by bumping the compression up to 9-1 (which they call for)? Does the cam really need it? I'll have the heads cut a bit, if popular consensus says to. TIA, Karlin.
