A 1977 MGB has less power than earlier ones, just 84bhp I think, so a Rover 2000 TC should be rather quicker. Contemporary road tests showed 0-60mph times of 14.0sec for the 1977 B GT (Autocar), 11.9 sec for a 2000 TC (Motor). I agree with Demetris' plan of attack. Retarded valve timing, caused by gradual stretch in the timing chains, might prove to be the reason for the poor performance.
