Which Cam do you like?

I have a '74 Scamp that I just pulled the motor due to the left bank smoking and found that it is either a performance or truck block- 4 bolt main & roller cam mounts- Ok please give me a little slack I'm new to this and classify myself as "dangerous" ... my question: which cam to use?
I want to build just a fun nice sounding driver. I'm not interested in quarter mile times because of the gas mileage ratio with speed. I had the stock heads rebuilt, have an Edelbrock Performer manifold & 600 CFM carb. Everything else is stock: 904, 273 buck gears, manifolds... I plan to mini tub and set the stance low so headers most likely won't work because A Body that I have seen at the shows their collector hangs lower than the sub frame .... so what cam would you use?
Comp cam's Thumper? Crane's 15000??

Thanks for your input!
