Pinging?
Just have a question for those who are technically savvy.
If I use premium gasoline (93 octane), can I advance my timing more? If so, what are the benefits? Are there any benefits?

Yes advancing the timing will make an engine produce more power up to a point. It will also run hotter so consequently the chances for detonation increase. You can try running higher octane fuel but with the horse urine they're trying to pass off as gasoline these days, I'd be real careful.

even if you went from a severly retarded setting, say ~0* BTDC, and increased it to say ~13* BTDC, your going to see MAYBE 10-=15rwhp/tq. your also going to pay what, .30 cents a gallon more, and potentially still ping under heavy loads, or high temps outside.... honestly, i dont think the cost offsets the benifit here.
anyhoo, my thoughts on it....might be nice to have 15hp in a 2500-3000lb car, but in a 6000lb truck, the seat of pants feel is going to be half.
good luck

Knock Sensors
We had a guy here about 6 months ago who's motor fried shortly after the rebuild. He said it never pinged but I don't know how he could have heard it, especially with open headers.
Is anyone good with electronics?
Would a DIY knock sensor be worth the effort?
