Get that effect with carbs too large but top speed not actually reduced. Would expect a Reliant carb to be OK. Acceleration in the gears reduces the obscuring effect of wind. As before the engine should still feel to be accelerating at the equiv of 50 in 3rd (30 mph). (Should pull steadily to valve bounce around 40 mph!)
Many things can make an engine flat in a saloon, including pocketed valves with very wide seats but would not expect to dampen a light special to such an extent. And the hc head should add considerably.
Did the car sound normal or "flat"? Is the cam standarrd? For a stock cam it is not dificult to verify valve timing to the accuracy likely to affect performance.
On my car certain exh leaks seriously sapped power. i dunno if there are layouts whch seriously detract.
