Factory Camshafts ~ 1968 340 '4-Speed' vs. Chevy '151'

28899205. I have one in my 69 and it is good for about a tenth and a mph with the stock setup. Plus it sounds rougher, as it is is, and idles worse. Not good for an automatic with a stock converter. Chrysler was right in not installing it in automatics. Would have been rough to drive with a 3.23 gear and stock convertor.
