Glad you're having fun with it, it really is a good car. I've never driven one completely stock but with a "big bore" kit, the torque is excellent. (86mm pistons). It never has a problem keeping up w/ traffic. I never pushed the handling because I don't know how one would throttle-steer a 356, (swing axles and <100hp), I know that it's somehow possible but did not want to learn on your car.
At speeds under the limits of adhesion, a lot of fun is available and this can still be quite fast. Like a 911, nothing can touch it on really tight twisty turns unless it's another car that weights under 2k lbs. You never, NEVER want to put larger or stickier tires on one of those cars. With swing axles, there is the possibility of *jacking* if the outside rear tire "bites" in a fast corner and then you will have sudden/extreme positive camber and the car will be the one doing a monkey roll. When they raced them back in the day on bias-ply tires 4" wide, it was like sailboat racing in terms of grip. You had some really skilled *drifters*.
