Hi Rick,
Yes, the MSD tech made that same parallel between the MSD RTR and the HEI distributors. I will be using the Innova light, though like you said earlier, I may not know if it is wrong. I guess I can verify, as I did establish TDC with a piston stop, and have a balancer cover with timing markings - no, I still won't know, IF the light doesn't strobe correctly. I do figure I am good with this setup, the odds are in my favor.
Regards, Doug
