HO Racing Distributor Curve Specs Chart
Does anyone by chance have the chart you can post that HO Racing used to sell with their distributor/Vacuum advance kits?
It showed a comparison between stock timing and HO racing recommended vacuum advance/timing curve specs. The pic I have is too blurry to make out. Thanks, Don

HO Distributor Curve
On a Sun machine, my HO modified stock distributor has 12 degrees all in at 2800 rpm. Did not check vacuum advance.
