Jim, an average of three 0-60mph times per fuel mix would have been more indicative of performance gain or loss. Easy to do with a copilot. Also some notes about the weather conditions, time of day, temp, initial and total timing and some indication of the mechanical advance curve, jetting, cam, stuff like that so we can try and relate some of your data to what's on other cars. Obviously the tests weren't all completed on the same day unless you did an awful lot of driving that day.
If you are running the 068 cam, your set-up will likely be the most demanding regarding octane in comparison to the other 400 engine combos.
If your charging system is running that high (18-24 volts), either you need a new voltmeter or you'll be frying batteries like crazy. Proper charging voltage is 14.7 volts.
Hey man. The results were so darn obvious. It would be totally rediculous to go into even more detail on this testing. We all know about how octane helps power in high compression engines anyway. I wanted to add a little 'rubber on pavement' observations since my engine and car were brand new. Just like '69. Go figure that when you get fuel in her like they had in '69 she would run the best. It's a no brainer.
Greg asked me to do it and I did. He told me that he was very happy with my testing and it helped confirm his suspicions. He has since done more testing and concurs that higher octane fuel gives him more power in his car too. His car also has high compression(stock 670's with original style pistons).
