Were S & M, or any other Mopar teams, dynoing their motors back then, or at what point? Just curious what the HP differences were in the span between say '68 and '73. The induction systems sure changed, then more radical camshafts, the newer design heads et al. Just curious to know what kind of true HP the factory SS/A and SS/B cars were making relative to what levels it had progressed to by the time pro stock was in full swing.
