but you left out part of it, all similar down low, which is great for driving around town but rather meaningless at the track, whether a straight line track or one with bends.
Point is the B series once modified at all has essentially the same power down low as the H, which is enough to have traction problems in the fwd set-up, but the B-series motors left the H in the dust up top. But then again the H is limited in its top end by a tranny that doesn’t shift for crap at high rpms B tranny’s can go much higher. Also the B series doesn’t have any of the inherent drawbacks of the H, such as: additional weight in poor location, bad axle positioning, low ground clearance, rather small aftermarket support. Instead the B also offers huge aftermarket parts selection and availability and also a wider choice of tranny selection for selecting gear ratios that work best with a given set-up and potential use.
