I converted my '70 340 from point to electronic ignition during the resto and now my tach reads around 800 RPM too high. Is there any way to correct this? I am using the orange control box and conversion harness that I got from YO. Thanks!

I would buy the calibrater as well unless you know someone you can borrow one from
