1969 Dart 340 cam selection help !!!

My 440 big block dart project has now turned into a 340 small block project.
I found a date coded 69 340 block had it broken down ex rayed and magna fluxed.
I plan to use the bottom end minus the pistons as they were some 11.5 to 1 old school stuff. I will use a 9.5 to 1 piston.
I will also be going with the edelbrock rpm aluminum heads, edelbrock rpm air gap intake and some tti headers.
The car will have a 727 auto with 323 or 355 rear end gears. Tourque converter stall speed is undecided.
I want the car to be mostly a street driver, but I may take it to the dragstrip to see what it can do. But be able to get up and go !!! and sound mean!!!!
I am trying to pick a Comp cam out of their chart that will work well for my situation. Not sure wether to go flat tappet or roller.
Has anyone built something similar ?????
What cam did you use ?
Tourque converter stall speed ?
Thanks
