I agree that there could be more torque below 4000rpm in the 360. Especially when using catback set with no valves. Otherwise fun and very drivable car that makes you smile and heads turn with it's ageless exterior design. Excellent boulevard cruiser too. I have no intentions to track mine, at least for now. I might add that it takes perfect shifts at exactly right rpms to hit that 4.5sec with a three pedal car. Few master that skill but most people don't. But so what! Doesn't take away from the enjoyment of owning this artwork of a car.
