Answer
If this were a stock Chevelle in decent shape, I could probably give you a pretty good idea.  However, with all the customizing to the powertrain and the paint, not to mention the problems (transmissions and upholstery are expensive to fix and/or replace), there's no way I can give you a figure that means anything.  You need to have an appraiser actually look at the car to determine its true value.
