Shelby not the first Cobra ACE Bristol

[Don]

Additional info in support of the engine name:

" This article first came out in two parts in the Crosley Automobile Club Quarterly in December 1976 and March 1977. I believe this article by Jan Eyerman is one of the most complete general histories to be written in a short article. So with ony minor changes from the oringinal two part article it was repeated in the June 1981 Quarterly. "


" For use in the Crosley cars, the engine was detuned to 7.5 to 1 compression ratio (still the highest in the industry) and delivered 26-1/2 horsepower. It was christened the Cobra-from COpper BRazed. The entire block, of 125 stampings weighed only 14 pounds. The crankcase was an aluminum casting for ridgidity and the inside of the block was at first plastic lined and later zinc lined for resistance to rust. The block was held together by press fits, spot welds and crimps prior to brazing in a 2060 degree F furnace. "
