I dont know about swapping cams. I dont even think it would run because of the difference in valve sizes and intake/exhaust ports. If you reversed the head maybe but then it wouldnt work due to cams now being on the wrong side.
If you wanted a turbo neon i think the mitsu head would be better simply to get more air over it and have a cooler setup. If you want all motor the neon is the way to go. I think the mitsu made less hp simply due to the setup of all the hot air getting into the intake manifold. And yes the neon dohc is overrated at 150 UNTILL you centerline the cams.

Most importantly it is a dodge block all have a pentastar on them.
