The most worshiped engine for hotrodders has always been the smallblock chevy until now. Now it is a LS engine. The smallblock came out in 55 and the hotrodders took it from there. The first things they did was change, intakes, valve covers, air cleaners etc in order for more performance and better looks. Same as now but some of us seem to think it is too much work. If you opened the hood of a stock 55 Chevy today you would be thinking of how the look of the engine needs some changes.......You Putz.
