I found out my 68, 302 has a roller cam in it, which means I use the 351 fring order. I found that out by trying the original timing order, and of course it wouldn't run.....I have an MSD ignition in it, and have no clue what the timing should be set at?? How do you do it?/ There is no vac advance to take off, any thing that needs to be done on the MSD box.

 

i run about 10 to 12 on a stock non roller late model 302...Just remember total timing is important too. should be between 32 and 40 i believe.Correct me if im wrong someone please.

 

As she sits right now, its at about 12-13, and when I rev her up she goes to 30.......do I drop or add from the 12-13???
