hi, i just bought a nice 68 conv. w/ a 327 3speed auto.... and i was wondering what type of gas i should use in it? i looked at a 69 before and the seller told me to use leaded gas.... using an additive in the existing unleaded.... should i only use this lead additive or what? thanx for the help

try using premium unleaded. if you don't have a problem with pinging, don't add anything else. when unleaded gas first came out, everyone freaked out about their valves wearing out but now we know you can go over 50,000 miles with unleaded and not have a problem. If you have a pinging problem, try 104+ or some other octane booster. Joe
