360 build advice for my '70 dart swinger

Thank you for the advice! Sorry, I did not mention it, but I am keeping the 2.76 gears in it, so I can drive it to north carolina at the end of august, but then I will replace them with a lower set of gears as soon as I get there. I am positive though that I would like to keep this engine on pump gas (preferrably 92-93 octane side) with no additives. I looked up the KB 107 pistons, and they look like the best bang for your buck, so I will be going with those. Should I keep the stock rods, and what rpm do they limit me to? Will they limit out, say for example, before the camshaft can not possibly make any more power? (the comp cam xe268h camshaft)...Could I even go with anything the next step more aggressive as far as camshafts go, but still keep it flat tappet hydraulic?... I am throwing out the idea of the lock-up tranny then. I do have 5 pre-1978 904 non lock-up transmissions and one 1976 727 transmission here in the garage that I could rebuild for this car...I also have the transgo TF2 shift kit for these transmissions too. Would you recommend keeping the stock torque converter? Or could I get away with a little more streetable stall speed, and If so, which torque converter would you recommend and what stall speed? My other performance related question is: Will the aluminum dual quad style manifold with two edelbrocks, or two holleys give me more horsepower than a single 4 barrel carburetor on top of a performance aluminum dual plane intake?
Thank you for the advice again!
