Base Timing & Rotor Phasing

Hey All,

I'm on the last leg of installing the dual quad setup on my 46 Chev. I have a question in regards to timing and rotor phasing.

How exactly is the rotor phased based on base timing? I've come across a Facebook video on the Fitech page and it says to put the engine at TDC  #1 -> drop in distributor -> mark rotor location for  #1 ->  rotate engine to 10 degrees BTDC and mark new rotor location -> rotate back to 0 degrees on timing tab -> adjust rotor to new mark for 10 degrees BTDC.

 

Based on the instructions in the Fitech manual, it says to do it a different way. Which way is correct?

Assuming you are phasing your rotor to utilize timing control.  This requires an MSD distr.  I'd follow MSD's instructions on phasing.  I purchased their adjustable rotor.
