Replacement 68 340 four speed cams

Wow!! When I saw the 68 cam specs i realize my cam is close to it. It was ground by a guy who used to work for Crane.
Adv duration and lift
Int .498 exh .512
Int. 274. Exh 286
113.5 LSA
In a 360 magnum, hydraulic roller
Stock block except for the cam/Springs, locks, retainers, air gap.
Did the stock 68 cam have a nice sound to it, nice lope at idle ?? What will more lift on mine do vs the 68 ?
Sweet spot for Mine is supposed to be 2000-6000. What is it for the 68 ?

BTW, this should settle any arguement
