David,
The owner told me that with the suspension and gearing, that this car drives straight when accelerating hard. I was concerned with that much power and low weight of the vehicle, that it would shake some (and thus be a little unsafe). But he said it does not. But he said the steering wheel does get a little shaky when slowing down, although.
For safety reason, I would think that the car would be not good for high speeds (above speed limits), but best for hard acceleration and for show. I did not see an air bag, for example. He said the curb weight was about 2600 lbs. and I thought he said that it had 485 pound-force foot of torque. I think that's the correct way to express the torque, but I could be wrong. I'm not sure what that would be in Newtons and meters.
So to answer your question, the car would have to be further heavily modified to modern safety standards, to drive with such a big engine (to be safe as other newer cars). But if a person just wants to have a nicer older car, with excellent acceleration and keeps the speed down to reasonable levels, then it would probably be relatively safe. I don't know...I don't think I would want to drive a car with so much power without air bags. There's no padding either. So much of the interior is solid steel.
