With number 13 I'd have to ask at what point would it be better to just get a different truck? I mean, it's one thing to tune the carb and advance the timing. It's another to pour thousands or tens of thousands into an old truck.

With number 16, a good balance will never completely remove all imbalances in a crossplane V8. But it may be good enough to not need a harmonic balancer.
