Holy Smoke, 30 inches is pretty good... I would be happy if my Monte gets 20 inches in idle and park...
This is the first time I hear vaccum related to ignition timing, but it probably can be done somehow...
What kind of vacuum gauge is that? What is your vacuum reading at idle?
I have similar timing values on my 454 BBC, but can not keep a 600 rpm idle, more like 800 rpm...
Buick Side Mirrors (yes, there is one on the passenger side) with Ford Focus power mirror controller in the driver side door...
And I also added LED Tunrsignals to the Mirrors:
If you are not too concerned about staying original, National Parts Depot has a hard plastic package tray with 6x9 speaker pods and a 3rd brake light (optional) integrated....
What's wrong with the 71 Grill?
The only thing I had to do to make mine fit perfectly is to elongate the mounting holes a little bit, no big deal...
I think it looks great...
Finally had time to work on the Monte this Sunday. First time since we moved south...
Finished the installation of the 92-98 Buick Power Side Rear View Mirrors, they work!
Next on the list: Florida Style Window Tinting & Installation of a Autometer GPS Speedometer Sensor...
Then putting the interior back together and cleaning the Monte...
