  • Mopar figures out heads and cams for MORE POWER! in the early 50s... Fires the first real shot?? Was this the true beginning of the horsepower wars? The Dodge D500 special edition comes out.. Performance packages become the rage.
    This would get them banned from Nascar with their hemi... #Hemi #Polyshere

    My Dad and I ordered the last Marine version of the poly available , we were marine engine dealers, they built it up from parts in stock at Dipetro Kay distributors back around 1978, pretty heavy motor and well made. much more expensive to make than the later 318 with stamped sheet metal rockers.

      Did they only ban the Chrysler 300? I ask because I recall Petty drove a Plymouth in 1960

    The poly-sphere engine kept many of the advantages of the original Hemi motor, while being simpler and less costly to build--a full Hemi would have been too pricey for the Plymouth market at the time (a Plymouth V8 cost around $300 less than a comparable Dodge with the Red Ram Hemi V8)

    hmm but what about the flat head? :)

    Once dealers were taught about the specs of the cars they would sell even if their background was in business administration or marketing or economics or the likes
    Today that would not be necessary, the average customer doesn't care anymore 😢

    According to Jay Leno the flathead engine cuuld be rebuilt by the corner gas station of that time. Simple design.

      I'm sure if you offered the guy at circle K 10k the dealer wants for the job now he would probably give it a shot :)

    i find it hard to believe that no matter what chrysler did to the old flathead 6..that it was superior to the ford or chevy 6

      The Ford and Chevy 6s didn't have inserts in the exhaust ports. All ChryCo 6s did. Ford and Chevy 6s didn't have chrome plated top compression rings. All ChryCo 6s did. An oil filter was optional on the Chevy, even V8s. Standard on all Chrysler built engines, including Plymouth 6s.

    I love how they make such different sales pitches to women than to men. What an insult

    • @jamesbosworth4191

      Not really, men and women often had different priorities. Even today, men like performance more so than great gas mileage. Many women care more about mileage. Men are more likely to put up with some reliability issues if the car is fantastic enough or cool enough. Many women refuse to put up with reliability issues.
