Holy Cow Hawk!
Next time tell me to sit down before I read something this unbelievable!
You actually used the light.
When you hook it up again, you can rev the engine and the display on the light will give you the rpms.
Then dial the knob on the light until the mark lines up.
I hear 36* total at about 3000 rpm's mentioned for SBC's.
Hopefully Cobalt will chime in here.
