70 SS 396 El Camino. The guy that had the Gremlin said it was stock (original engine) Neither car was in "stock" trim. (It's how we rolled back in the day).
The Gremlin they list as a "muscle car" is a 1978. By no means muscle. What beat your 396, well that car was prepped with an after market engine etc.. Read ab7fh post above.
