to go brain or no brain??????

[RootBreaker]

ok so I need a cam for my truck...
comp cams xtreme 4x4 cam is $250 plus gaskets.. maybe $325 total...

however I can get a fuel injected 350 for $350..my father knows a guy that owns a junkyard....

anyhow.. I like my truck being stupid.. however is it better for me to get the other engine? all the wiring and do a full swap?
then I will have sensors and crap....

also if so what would be the ideal swap? car, truck, type?

Thanks
Still trying to figure this stuff out...
