The engine from the AMT '72 Chevy pickup pretty well has everything you need except the headers and AC compressor, Right valve covers, intake manifold, automatic tranny, etc. The compressor is in the Revell '32 kit I assume you'll be using, the right carb too.
For the flames, I'd use a good side on pic of the car, print it out the right size on a large self stick label and cut it out to use as a mask.
OR just print the pic on white decal sheet, cut out and use.
