Some visitors to this site will wonder about performance. I'm not one of those people who likes to break speed limits, so I haven't attempted to find out in practice, but published figures quoted for a 1987 Chevy Camaro 350TPI IROC-Z with a very similar specification, (thus mechanically pretty much the same car) are: top speed 'well in excess of 140mph', a standing-start quarter mile time of 14.5 seconds. 0-60 time 6.2 seconds.
In my own experience, driven carefully, the car returns about 22mpg, but that drops off quite quickly if the throttle is used firmly.
