Gauges Quality
I would like a “good” quality older gauge for my car. Just wondering how good/accurate these Sun gauges and Tachs are? Specifically the Sun “GREEN LINE” series of gauges, and the 10,000 RPM tach. Do not want to put a high dollar ZL-1 build in the hands of a dollar store gauge. And YES, this will be a 8500+ RPM motor that will see plenty of time on the strip as well as the street.

Re: Gauges Quality
Sounds like you'll have a lot going on. Tyically the Greenline tach require a sending box. I've only seen them go as high as 9k, but maybe there is a 10K.
In that situation using a modified ZL1 I would probably recommend sending the tach out to be "updated" with modern electronics and checked for accuracy. This way you don't have to worry about how some sort of multiple spark and/or CD ignition will affect the tach. The Sun tachs were one of the most accurate tachs of the time, but Rosen did make comments that some CD ignition systems were less compatible with some tachs and that is why he used the GM hood tach on a few.

Re: Gauges Quality
Have you thought about the repop Stewart Warner greenline gauges? I think their tach only goes to 8000 though. Vintage look with modern internals.
Same goes for the repop Super Tach, only 8000 rpm. I haven't used any of these, so I don't know the quality. http://www.summitracing.com/search/?...auge&dds=1 http://www.summitracing.com/parts/SUN-SST802R/

Re: Gauges Quality
Hemi, thanks. Hadn't seen them. Was/am leaning towards the "SUN" Tach as that's what the Yenko's used from the dealership. But like the "green-line" SW gauges for there look. Wish they had Oil Temp though for my set-up! We use that also to get an indication if a bearing or somethings is starting to go away as there's in no "cooling" effect like the water. So if under normal conditions you notice that the oil temp is 5+ degs higher, we start looking at things a little more serious.
As for the tach. Too bad these are only 8000 rpm deals. From what we know with a vintage Lemans motors we've sent to France, they like to see about 8400-8600 rpms when the needs arises.
