That may be the deal though, I hadn't thought about it before. I guess that a couple of degrees might do the trick without losing too much HP or torque.

Lamin8r have you tried setting your timing back a mark or two?


Thanks all! I'll let you know how it works! But for the time being I'm heading back to my "snake oil" supplier and get another case

Yes,Eric..we did..still ran harder with the booster,,hauled some serious a$$,as you would expect with 451 inches of mad Mopar...and a fair bit of fruit stuffed inside it..

Hey, just wanted to let you know how things went with my snake oil!!!

I did get another case, but felt like I was sneaking power additives in the dead of the night!

So the next time I tuned it (needed it pretty badly too) I just retarded the timing a bit, cleaned up the carb, and reset the idle.

Yahooooo, now I'm running on 89 octane without a hint of a knock and just a little bit milder than before!!!

But when I was messing around (before the tune up) I came up with another question...

I used to use Chevron 93 octane, thought techron was the cats meow, and had to use octane adder to get rid of the detonation. But for other reasons, I changed over to Gate gas and was able to run their 93 octane without any knocks?? Tried the 89 octane and the knocks were back...before the tune up anyway.

So there must be a difference between Chevron and Gates fuel!

Anyone else notice any difference between any fuel? What is your favorite?

Inquiring minds have to know!
