Hot Rod Magazine HP 273 build

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?

Testing the Mopar 273 Power Pak on the Dyno - Hot Rod
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.
