'67 Nova SS, 327-275hp 4-sp, Maybe #s?
 

Long-term owner since 1974 - I love buying cars like these, and I'm digging the late 1970s World of Wheels vibe. Assembly date on the block seems to line up with the build date, so it might be the original engine. I think this would be a solid deal for somewhere around $20k. Unfortunately, the screwed-on VIN plate and trim tag are a bit of a buzzkill although I doubt the seller was doing anything nefarious.
