I'm not sure but I've seen it somewhere forgot what forum about advancing timing. I just want to make sure I'm doing this right before screwing up my car. Advancing is for top end purposes right ?, and retarding is for a 1/4 mile pickup if u want a fast start. But what's the safest degree I can advance timing my car. I've also read by advancing timing, the engine will now runs hotter. So, can this attributes to overheating problems down the line ?
