I know exactly what you're saying. My builder is just saying that whether the cam design is advanced or retarded, then the spark advance may need to be set differently for best performance.MORE BS - where does this all come from????? Argh!
Ignition timing ONLY has to do with when the spark plug lights. The distributor may be driven by the cam gear BUT, the distributor rotates freely and can be rotated in any position to set the timing wherever you want, regardless of whether the cam is advanced, retarded or straight-up. Just because they share the same word of "timing" doesn't mean they are referring to the same MEANING of what "timing" is.
