I had a 79, Z28, black, ordered new. 3 speed auto. Back then it seemed to go pretty good. Better than the HP numbers indicated. In true GM fashion, they had the 5.7, even in the Vettes, running thru one cat. I put a test pipe on it which back then were available anywhere. Dunno if it did much. Overall, I have fond memories of the car. I got the driver's seat "option" that allowed for about a 5 degree tilt on the back rest part of the seat as seat backs did not recline in most cars.
