years ago had an A14 in a 1000 2door. had around 85-90hp at the wheels. this was with big cam, double valve springs, 1600/510 recut exhaust valves, ported polished A12gx head, flat top pistons gx cast exhaust manifold 2.25" free flowing exhaust. this was all fed by twin su's, which were eventually swapped for a pair of 40mm dellorto carbs. went harder and smoother with the dellortos but never got it onto a dyno.

and i can back up what dodgeman said ..... plenty of times i nearly had to rush home for a change of undies was a great power to weight and with a decent set of brakes to stop it, it was definitely one of the most fun cars i've owned
