The 426 Ramcharger - King of the Drag Strips in '63 In mid-1962, the bucket-seat Dodge Polara 500 Sport Series was introduced. Top engine option was a 413 cubic-inch, 410 horsepower Ramcharger V8.
For 1963, NASCAR and the NHRA announced an engine-displacement increase to 427 cubic-inches for Super Stock cars competing in acceleration and speed-trial competition. To stay fully competitive, Dodge replaced the year-old 413 with an Ultra High Performance Ramcharger 426. This 426 featured dual four-barrel carburetors and a high overlap cam. Horsepower was 426 at 5600 rpm. With the additional High Compression package, the compression ratio was a sky-high 13.5:1. It was not recommended for everyday street driving.
The Ramcharger Dodge was the king of the drag strips in 1963, rewriting many NHRA track records. For 1963, just 28 Polara 500 convertibles had the Ramcharger option, but only seven (including the car shown) had the High Compression package. In 1964, four more Ramcharger convertibles were built, but none had the High Compression package.
