I know the lift and duration. Just wanting the actual valve opening and closing events. I can get it when I degree the cam. Just wanted to know what it should be. I guess Chevy doesn't publish it anywhere?
I know you said you know all these, but I'll post them for everyone else to see.
The lift is .525" with 1.6:1 rockers, .492" with 1.5:1 rockers
The duration at .050" is 218*/228*
Advertised duration is 279*/287*
The lobe seperation angle (LSA) is 112*.
I don't know the Intake Centerline (IC or aka ICA). I would imagine it's 4* advance like any other production SBC cam, which would make it 108*, but this is where learning how to degree a cam the proper way pays off.
Input this info in any program like Desk Top Dyon or Engine Analyzer Pro and you can find out all the other numbers.
