I agree 100% with JB about believing magazine articles: Don't! & as for being an old-schooler, let me give you two examples (both Chevy's, but relevant). My 1970 BB Monte runs ABSOLUTELY FINE on 87 octane & it has 10.25:1 compression. There's no power difference with a different gas, unless it's very hot or humid, which effects cylinder head temps & causes pre-ignition (or unless it's 104 race gas). My 1994 LT-1 Caprice has the computer reprogrammed & an LT-4 knock module & runs no differently on 87 or 93 octane. These are my experiences & I think I have infinitely more experience on the strip or under the hood on both of these cars than most casual enthusiasts. My point is, carbureted or computerized makes no difference: Minor octane differences WILL NOT affect performance like the article describes. Period! We don't need to test it in the Bullitt 'cause we know this to be a fact. Read up a little on octane ratings if you don't believe any of us. I'd be more than willing to find some web sites with good descriptions & definitions if you'd like. That's what I like about these forums. It gives people a chance to talk with others who know more about certain subjects & learn something. Personally, I've learned a ton about fuel injection, computers & ABS over the internet in the last few years.
