Hi Gang..what's the verdict on ignition timing? Here are the details: 270 deg.
duration cam with 108 deg lobe separation, stock rocker arm ratio, compression
upped to 10 :1...maybe a bit higher, vacuum system disabled, running 86 octane
smoothly enough, Pertronics...no points, Lucas high-output coil. I'm getting
some occasional back firing through the carbs when pulling away from a dead
stop and am trying to figure out what's causing it. Currently the timing's set
at about 14 deg BTDC at 825-850 rpm then idle is upped to 900-ish, which seems
to have helped a bit. Thanks as always, Colin '75
