360 build for dart swinger

300-350 hp 360 engine would work well.

You can find decent iron factory heads for 500ish if you look around, ready to bolt on. Put a decent intake/carb, well sorted out ignition, headers and a 702/703 voodoo/XE268h comp cam or similar and it will be capable mid/high 100's in the 1/4 .

If you want fresh heads, go with the iron 2.02 LA-X head from brian at IMM. They work great, flow well and stomp a mudhole in stock ede heads performance wise. The weight isn't an issue when you make a bunch more power.
