Replacement 68 340 four speed cams
As I went thru this thread again lots of folks say there is better stuff out there but I owned a 68 F/S 4 speed car. All stock except the carb. and that son of a gun just would rpm all day long even in high gear. I've used this cam a lot thru the years and no one ever complained but I got a lot of thumbs up from my customers.
