So, we seem to have found the source of our blown pistons and ring lands! Our distributor (off a fresh rebuild I might add), does not have enough vacuum retard at WOT. Turns out we were way too far advanced (about 38-40 degrees) under load.
My question is, how do you adjust the vacuum unit? The advance and retard work when you pull a vacuum on them. However, I suspect that the adjustment screw is not adjusted properly. It is almost all the way out. Does anyone know how to get this speced right? Thanks for your help, Chris |

Shops used to have a machine that you could put the dizzy in to adjust the advance curves. Hmm, I haven't seen one in awhile soo look around for a shop who does/can.
