I would follow 96SC, being the wear factor, the broken chain being you hot rod the sports car. So, like a bicycle chain, you ride over one bend (sprockets) with the chain's pin feeling that tug on one side only, she wears out at the internal pins of the chain.
There is also a cut-box within the spark box, so if your timing falls out of spec, the cut box sets your ignition to retard, lowers the power pulse, saves the retard/advance timing is she is pretty much safe to drive the lit fuse after say 70K worth of hot throttle application.
