I don't get the magazine but just caught this. Looks like their dyno numbers were damn close to the factory's 235 horse rating. They added headers and dyno'd it again for a slight increase. There's some D Dart info at the end of the article. @ddartdude Alan,have you seen this yet?
Yes....it's the same article that is in the Feb, 2020 issue of Mopar Muscle. Looked around the Web for Steve Magnante's contact info to correct some of the D/Dart info. No luck.
