To advance or Not
Won't work on a magnum engine! All the bushings to center it on the crank are to small for the bolt!! I bought one last week and tried to use it. I did make it work like everything I own use or buy it took tweaking!! It was my first cam degree and now I see how easy it is to do you shouldn't skip it.imo. My lunati cam and Hughes timing set were right on. I would suggest a positive piston stop! There's prolly 10 degrees of piston dwell ATDC and maybe 5 degrees on the cam lobes centerline. A lot of guessing if you don't do it correct.
