If you haven't seen it. www.comediansincarsgettingcoffee.com I think this is a Jerry Seinfeld production.
I thought Jerry was more car savvy - a 340, six pack, hemi? Most anyone knows the 340 to be a small block, with wedge combustion chambers. Wish we had that nice, windows-down weather.
Who knows, maybe they destroked and sleeved a hemi down from 426 to 340 cubes. And the six pack was available on the 440 wedge engine...........really mixing up all the old engines...
