Another “which camshaft” post

As far as exhaust I do have the 68 340 manifolds with TTI 2 1/2 system w/H pipe about as good as it gets without headers.
Also 3.23 gear w/ 26” tires may go to 3.55 but I want to be able to cruise on the freeway(the car came w/ 2.76 peg leg so already an improvement).
The motor I think was originally a 2bbl so the cam is pretty mild, the idle is just too smooth
The stage 3 cam is in stock, but I will give Ken a call on Monday to see what’s up there.
