We have a 69 SS/RS here in Sweden that is supposed to have a dealer installed 427 by Brahms Chevrolet, Palisades Park in New Jersey. It was ordered for racing by some Carleen and sponsored by Brahms according to the story. It was raced at Englishtown between 69 and 71. The present owner here has some documentation like the service book wer it says:
SERVICE INSTALLED 427 HIGHPERF ENGINE FOR OFF HIGHWAY USE ONLY. VOIDS THIS CONTRACT OF NEW VEHICLE WARRENTY. Then it has the VIN 124379N550532 and a stamp: WARRANTY Brahms Chevrolet Company,inc. date 3/21/69 Void
Anyone knows anything about this dealer and possible the car.
