Tim,
It would depend who is standing on the other side of the counter. If it's some kid that only knows how to push bottons on a keyboard , all it would get you is a blank stare. If it would be someone that had been selling parts for 10yrs, it would probably get you what you needed.
Or you could just tell them you need an HEI module for a 1976 chevy nova with a 250 cu.in. 6 cyl engine.
