Not really. Computer controls the idle speed. Need a cam with more overlap, but then not sure how well your computer will respond to that change.
Also a bad vacuum leak will cause rough running like you describe.
j/k, you don't want to do that.
Drop in a 5.0L with a B303 cam or something with lope.
