All the drag race SD cars came with alu exhaust.The circle cars came with a stamped steel header.I saw the Demetrie car which was not a swiss cheese car with plexi windows.I dont think someone with a swiss cheese car would have moved the battery from the trunk to the front,that is the big give away.The engines in the swiss cheese cars were the same as the rest of the SD cars.ALL the 13 S.C. cars were alu.Not all SD cars were alu.
