Strength is no worry as it is only a PRC motor (as wild as I can go though
12:1 comp at the moment, stroked to 1999cc etc) so it isnt a box breaker,
but I need the ratios closer as rev range is all important. There is
nothing so disappointing as getting out from a car with an Option One and
getting into something with wide ratios.
