GM CAM valve timing points

I sure would like to know what the Intake valve closing point is on a stock 95LT1 cam which is 202/207 duration 116 lobe separation.

It's got to be around 65 or so.....

GM part nut GMPT 242 BC stamped on the cam...

Re: GM CAM valve timing points

Yea, I can't find squat on the valve timing points. My static comp is 10.7-10.8 somewhere, and I used the stock cam for my daily driver and it's riding the edge of 93 octane capability. If the fuel is good, I don't see retard, but slightly reduced octane, it's starts spark knockin a little.

Just maybe someone will have this data...
