well, who really cares if the chart won't work on some crappy Chevrolets or Fords? The chart is for our stock or stock-ish B & RB motors, LA motors, even 360 Magnums. And believe it or not it'll work on traditional Chevy Mouse and Rat motors too!
I know what it works on. Believe it or not I've put together a couple of Shivvies and a Ford here and there. And a reverse rotation Y block marine Ford.
YOU might care if you are trying to help a friend out with an "alternative engine", just pointing that out. What if you don't know this and your chart gets damaged? You backfire the carb, etc, or "steam" it off with a radiator "event?" Your chart goes away, and there you sit, ??hmmmm??
I guess you didn't notice the part where I mentioned...........
