Not sure what he would have meant by "double barrel" unless he meant 2-barrel ... prob. is, the (real) 442 was never offered with a 2bbl ... otherwise it'd have been a 422!

I'd have to think he said ... or "should" have said, 4-barrel (4 bbl).

BUT ... the "real" 442 never had a 350 either (unless he meant 350 HP) until 1975 .... but they were just a dang de-tuned, no lead gas Cutlass with 442 badges stuck on 'em by that time. Not the 442 of the "muscle car era". Heck, they didn't even have dual exhausts by that time ... just two outlets. NOT what I'd call a 442. They even had a dang 442 6-cyl. that year which may have (probably had) a 2-bbl. I didn't pay a bit of attention to them in the later years because they were nothing more than grocery-getters with 442 badges stuck on 'em. Heck, they even had automatics in 'em by that time.

Oh yeah, if you've shot a single barrel shotgun .... it shouldn't be too hard to figure out what a "double barrel" shotgun would be.
