GTS 340 auto, Charger R/T 440 4-speed, Superbee 383 auto, GTX 440 auto, D100 (new front frame 5.7 hemi - in process), Formula S 340 4-Speed A/C (it's green), 383 auto Roadrunner (maybe a hemi - waiting) and a 68 W200 Power Wagon.

I can't attest to the reliabilty of this source but I found this report online http://resources.metapress.com/pdf-preview.axd?code=v714477wv0462587&size=larger (click on the page when it opens. It'll get bigger!) They said it ranged from 91 - 97 in 1958 to 93 - 103 in 1970. I didn't read the whole thing; too many big words LOL.

Everybody's premium had 100 octane. Gas wars were not unusual and many times I got premium for 25.9 cents a gallon. Your life is not my fault. My life is none of your business.

Research octane is about 8 points higher than motor octane so 100 octane in 1970 terms would be about 96 octane with today's R+M/2 ratings.

I mean as a kid in the 60's I remember smelling the WONDERFUL aroma even as you pulled up to the pumps. It was heady, clean. Smelled like it would Taste good. Nothing like today. Anyone else remember that or am I just in my own little world?

But you are right in that it did have a distinct smell to it.

The 260 in our area was 104 octane and most of the guys who raced at "75 and 80" and "Aquasco Raceway" in Maryland used it. You'll never see that octane from a pump again!

But you are right in that it did have a distinct smell to it. More than once. A kid learning the basics of siphoning in the 60-70's was a dose of tetraethyl lead! I am ok really,,,,no last effects......really, no really.

That night was brutal, on both ends, for me. I have used pumps ever since. Your life is not my fault. My life is none of your business. Speech is free only if you agree with those in control.
