Trouble Timing my 340

Oh, my crane cam 226 / 230 cam shakes the vacuum needle gauge at idle as well, it pulls around 13 at 900 and idles in gear at 700

The way things are around here - one min red lights and traffic that slows down for green lights so they can stop for each red light, ah how the motor idles and runs at low rpm matters more then anything else.

1,200 idle speed is normal for hot street cars, for me that is too high but again those 4.30 gears will help out. Good mufflers are a must, IMO or everybody is going to looking at your car at each red light wondering why your engine is so loud
