Pro Flo 4 Timing

Once I straightened out the phasing, the system is flawless. I also shortened the distributor to fit under the wiper motor. I’m at 20 initial/30 total. This is similar to where I wound up when I ran this engine on the dyno before installing. 410,11:3, hydraulic roller

Do you have to use the Edelbrock distributor? I have an msd pro-billet locked out with the adjustable rotor already. I'm running fitech, but am considering swapping to the proflo. I didn't want to have to modify the dist. or the manifold tho.
