Intake centerline for a stock truck FE cam ?

Hi,

I am rebuilding a 360 FE and replacing the cam with a Sealed Power #643. This is a stock lopo cam with under 200 degrees duration at 0.050", but I want to make sure the timing will be correct by degreeing the cam ( have a 9 position gearset).

What would be the correct intake centerline in degrees for this ( stock truck FE cam) ?

Thanks !

That 7,7 is a true ratio,calculated using deck hgt, piston valve notches, head gasket and head cc.

My 1966 390 GT was supposed to have a 10.5 ratio from the factory, when calculated it turned out to be around 9,9.That engine was " factory sealed" meaning I was the first one to open it after 1966.
