Total Timing?

Hey,

I have read a few different RPM's that total timing should be checked at.

I dont know if it makes a difference, but its a 340, purple cam, headers, 600DP Holley..

I just want to clarify what I should do to properly check and set my total timing:

First, warm up the motor.

Then unplug vaccum advance from the distributor?

Then set the rpms to 2000 or 3500??

Then turn my dial on the timing light, til the mark on the balancer is at 0, then whatever the dial on the light is reading is the total timing???

And I want it to be at 35 or 36 or 37 degrees??

Thanks,

Shane
