cam suggestion for hi-comp 340 and 3.23 gears

Hi guys, a bit of a cheeky request as the car involved is B body, 73 Roadrunner. I did ask over on forbbodiesonly, but only got one response which was helpful, but Id just like a wider range of options.
Car has real 10.1 compression with the smaller valve J heads, stock rocker gear which id like to retain, original 340 manifolds and dual pipes. Rear is 3.23
Looking for a good cam that will pull this heavy old B body (my old dart is now sold), I can upgrade convertor if required. Car is for street use and has power brakes.
Thanks in advance
