Msd multi step retard. if you buy a good kit( NOS is not a good brand out dated) you don't need a ton of timing taken out. Look into Zex , NX or the Wilson manifold brand. I have never used a controller. they are good if you have traction issues for delaying the "hit"

I loosen up the bolt that holds the distributor down and spin it.
Actually, I don't retard any timing. Just run good gas. I tried retarding the timing but with my Hi-tech tune it didn't like it when I turned the distributor.
