- My problem is that over long runs at 3000+ rpm in OD, I am getting some pinging and overheating. Everything below 3000 is great. I want to avoid advancing too much, but I am thinking that maybe I nee

- FWIW, it has been my experience with high compression pistons, in any older engine (read as cast iron heads) you will need a different vac unit. What you want in the end is for less total vacuum adv

- Hi Olin, Depending on the state of tune, you regraph the distributor advance curve so that the engine has total maximum advance of around 34 - 36 degrees at around 3,500 rpm engine rpm. If you've got
