Help me sort my combo

So its time to freshen my 20 year old build. Specifically I'm looking to improve my cam choice and match the torque converter, which my present combo doesn't. The goal is a zippy street ride that doesn't embarrass me. What I've got

69 dart gt convertible with frame ties and SS springs
3.55 sure grip
727 rebuilt auto with shift kit
2500 boss hog converter

400 from 76 New Yorker rebuilt
polished cast crank reconditioned rods
l2388 F 40 trw pistons yeilding about 10.1:1
Mopar 509 purple shaft cam
Stealth heads gasket matched
Edelbrock rpm performer intake
msd distributer and 6al ignition
Speed demon 750 vacuum secondary
a body big block exhaust manifolds into 2 1/2" dual exhaust with crossover
Be cool rad

Not trying to squeeze the last HP, just reliable and responsive. I'm hoping to hear from similar combo's that work well. Thanks for any and all input!
