Maybe one last question, what is the intake lobe centerline set at ?
************
OK maybe one more, what does the ignition timing curve look like ?
No idea on lobe centerline. It is whatever GM set it at. There is no easy way to check this stuff since the engine doesn't even have a TDC pointer. You can't set the timing on the engine since you don't know what it is. You just have to trust that GM built it correctly.
The ignition curve in the engine at the moment 25 at idle and 32 at WOT. There is another 6 degrees of vacuum advance built in. But who knows what the actual timing is since we can't check it.
