Predetonation pinging and rattling
I am working with a friend on his truck. 350sbc with HEI from an '86 Blazer. We have it timed right at idle. However, when he gets up to speed (45+ mph) and is accellerating, the valves start rattling. I think he is geting predetonation from the vacuum advance. Could I be wrong? If I'm correct....what is the best way to adjust it? Not my wheelhouse.
