.480/230 cam in an 8.5 CR 360?

Good. So that means when I get my CR sorted, I'll be back to talk more about how much I should bump the cam forward. However it works, I'll shoot for at least 9:1, or more if that's how the parts work out. And aquire an adjustable timing chain set, as this one's not.
At 9:1......a MEASURED 9:1 and not "bench racin" 9:1, I'd go 4 degrees advanced. That would be 105 ICL.
