67 Nova, I have been a owner of a 1966 nova since 1988. The car will handle the power. The problem i had with High HP in my car is that the Front suspension, and Brakes are not good enough for high speed. So if you have the ability to not go to fast, then no problem. However, i know i dont. Upgrading the front suspension is on my " to do " list. I stopped driving mine about 13 years ago when my son was born, and it scared the hell out of me at about 110 mph. ( no he wasnt in the car with me ) Looking back on it i would have started with the suspension/ brake upgrade, and then went to the High HP. but those cars sure haul ass with a little power.
