Overlap Triangle

Danny Bellmore said
I will give you what I have from the cam card.
Comp Cams 20-718-9
Gross Valve lift (in 654) (ex 655) add 1.6 rocker arms.
Duration @50 (in 269) (ex 276)
Lobe Lift (in .436) (ex .437)
Valve Timing @50 (in open 45) (in close 77)
(ex open 81) (ex close 48)
Lobe seperation 106

I'm going to assume that Comp called for a 102 ICL. So 4 degrees advance.

To center the overlap triangle you need to install the cam at a 105 ICL.
