Well, I pulled the trigger last night, so I guess I have bought a coach.

Now to get financing, insurance, etc. and retrieve it from over 450 miles away from home.

I see from info that it requires 91 Octane fuel. Is this current 91 stuff or the OLD 91 stuff? If I remember correctly, current 87 or 88 is about equivalent to the old 91 stuff.

Mac,

Welcome to the group/cult/asylum...

Octane numbers from years ago can deceiving as the recommendations are usually not specific as to Motor or Research number and the two are run at different speeds and temperatures.

To really answer your question, the Olds 455 was built with a CR at or about 8.5. That should not have problems with current regular grade fuels whether containing alcohol or not. If you hear it pinging, back off the throttle until you can get somewhere and back the distributor down a few degrees.

As to tires: There has been much discussion here and some have had failures such that the tire age was the major issue. It may cost a some serious coin to change out 6 tires, but it has a good possibility of being less expensive than the repairs that may be required after a tire throws its belts.

And as always. . .

May the Good Lord bless this coach and all that set forth within.
