The ever-so desireable 308 Heads

Is this the movie where the car was buried under a cement slab and Lee dug it up and ran it? I’ve been thinking about a movie like this for a while and couldn’t remember the name. I have a bad habit of remembering movies from my childhood in the 70’s and go on this ridiculous search to find it! Last one was Hot Rod 1980!

Sorry for the derailment :)
