[quote=LONGHAIR;5950317]How much vacuum does your engine make? At idle? At the pinging point?
It seems like there is still too much vacuum advance at that rpm.
I have a vacuum pump, but not a vacuum gauge.... its on the list...
I might could use the gauge on the vacuum pump somehow, I will look into that.

With it capped off I did still get around 18 mpg's, but I am running a stock cam, 700R4, and 308 gears. Like I have said before, I feel for you. A engine noise is as bad as door glass without weatherstripping....it will drive you crazy! Lol.

18 mpg!!!! nice, this isn't downhill is it? ...lol
Nobody in town has a adjustable vacuum can with a limiter plate, so I would either have to order one or take it out of the mechanical advance.
I read some about making one, I have three vacuum cans to use, so I might try that.
Thank you everyone and I will update with more info asap.
