1969 Dodge Dart 340 f(stock ) specs

Big difference between what was legal then vs. now. Then, stock meant stock. Trim, interior, etc. Engine had to be the right castings, cam specs, valve springs, carb, intake, and I don't think anyone was doing acid porting. Or spinning them 8000 RPM. Wasn't all engine. Plenty of work done to the car as well.
