Your a little limited with the lower compression but thats fine as you will be running pump gas. With a manual trans, your axle ratio and tire size you dont need a low end cam to fry the tires.
Personally I would have a custom cam ground but good cam cores a hard to find.
If your thinking about out of the box performance try this on for size. Hydraulic Roller Camshaft; 1964 - 2003 Chrysler 273, 340, 360 2400 to 6300 Howards Cams 712105-10 | Howards Cams
