Now that I've finished breaking in my new engine, I'm ready to fine tune the timing. For the record, I'm running a 351W with aluminum Victor Jr. heads, hydraulic roller cam and roller rockers. My concern is that I won't be able to hear sounds of detonation over the side exhausts if I advance the timing too much. Is there any way to tell if the timing is advanced too much if you can't hear the engine ping?
