True....I've seen quite a few of those in Diplomats in the boneyards. That's what I meant though, by "earlier"......meaning back in '67 through '72 or so. The 318's were rated at 230 with a 2-barrel and 9:1 compression. They would've been a cool setup with a 4-barrel, dual exhaust and maybe a little hotter cam. Chrysler had to have tested something like this at one time or another. Would've been another cool option for a Duster Twister or a Dart GT.
