'68 4-speed cam?

Are you saying you could put that 268 cam into a good engine with stock valve train and springs without any harm?
Looking for a slight extra bump in mine without doing a complete tear down.

Yeah, on NEW factory 340 springs. I consider springs in the same way as lifters. I won't put a new cam in anything without knowing the springs are in good condition and adequate for the lift. The Comp 268 list a stronger spring than the factory 340 spring anyway. As cheap as springs are and as easy as they are to replace, there's no reason not to do it right.
