Tunnel ram 440

Ok I just scored a sweet deal on eBay I bought a tunnel ram complete with 2 Holley vacume secondary carbs for 325$. Any way I have a 77 440 engine that's rebuilt to stock specs still low comp and bored 20 over. The engines in perfect shape so I don't really want to replace the slugs. I'd like to run the tunnel ram but don't want to be making a mistake by throwing on a motor that can't back it up. I'm considering running the mp 509 cam in it but like to see if yu all can direct me in the right direction for a cam that will be good for low compression and the tunnel ram. What gears and size stall would be best too? Thanks in advance for your help and sorry if my question is a dumb one. :burnout:
