318 with 360 heads and compcam build help

Okay so say I sell the comp cam kit and the 360 heads and the 360 block and another 273 motor and a few transmissions I’ve got in my garage now I’ve got some money. And my parts list looks a little different now it’s a 318 with 318 heads a chinesium 4 barrel intake a couple Holley 4 barrels and a 4 barrel edelbrock carb I want some more performance what do you suggest I do to raise the performance?

Ok, what raw material do we have right now? Engines, what year 273, transmissions, rears? All to go in a 70 Swinger. Is the 318 in the Swinger running now? Pictures? Sell the cam for sure.
