Rob, yes its from PD and yes I opened the gap, I ran one of their Race units in my dirt modified on alky, with #145 jets all around, worked great, the vette runs smoother than it did with the point setup, MSD makes good stuff but if you want the CD effect you have to run a spark box and I had spark box issues in the past, if you want smooth operation on the street you should always run a vac adv, these young guys think they are going to go faster without it, Ive done all that s
t, it doesn't work that way on the street, when you get your unit it will have your built in mechanical adv. scribed on the base of the dist. add you initial static timing and that will give you total timing, good luck.
