Premium. If it still pings you may need to retard the timing and use an octane booster.

I don't have the car home yet, I am still trying to find a reasonably priced way to get it shipped from Nova Scotia to Alberta.

He bought this car brand new in '71 and has owned it ever since. All the serial numbers of course match and it is absolutely mint. It was his baby and I am proud to call it mine now.

WOW! My mother had that exact car and color combo back in '71 right down to the Rally II wheels. Hers, unfortunately only had a base engine but was sweet to drive. Can't imagine the fun you are having while driving and preserving this 455 car. Give her all the octane you can get!
