So, question still remains, anyone with Pentastar experience in Lemons?
Off the top of my head, I can't think of anyone who's run one in Lemons. Maybe we've had a V6 Charger or something like that I don't remember, though I think the 3 or 4 LX-platform Chryslers have all been Hemi cars (which demonstrably do NOT dominate at Lemons).
Not that you don't already know this better than anyone else, but that particular loophole is completely unexploited and most Lemons loopholes are largest for the first person to exploit them.
Fun Side Note: When I briefly had the '78 Magnum and was working for Roadkill Sponsored by Dodge(tm), I floated the idea to my editor about Dodge sending me a Pentastar V6 for Lemons duty a la Dodge sending F&F a Hellcat V8 for the General Mayhem. That idea didn't get far because Dodge killed their sponsorship of Roadkill, followed not long after by Discovery killing Roadkill's editorial arm and the Roadkill-Lemons connection by proxy to say nothing of the Magnum folding itself in half on jack stands and therefore going to the scrap heap. But the idea was actually pretty sound: 1.5 times as much horsepower and twice as many gears as a stock B-Body Magnum and less weight than a modern Charger. Probably would have gone reasonably well in a straight line, at least, if it had ever worked.
