[ROVERNET - UK] 4.3 bhp output

 I have now seen two racing Rovers up close- both were very quick and
both used the standard diff, with some suspension mods, including
anti-sway bars.

Thanks Bill, for the additional info.  After reading your description of
what was done the the body monocoque structure, it is no wonder that the
car flexed just pushing it across the garage floor!  I am also
astonished that the Rover 3500 diff was able to transmit the torque from
the 364 hp factor prepared motor.  I am even more astonished that
someone was able to identify that 'mishmash' of parts and know that they
could assemble them into the motor.  The chief mechanic must have been
some sort of evil genius:-)
