Rear shock length

Another silly question sorry guys

What's the general verdict on rear shocks for optimum length

I run mopar b body on my dart, and I think they do the job, as the rear body lifts showing the tyre, but........big but

Would it work better with say a truck shock? Or a 21" plus shock

My 60 foots are good, hooks well, lifts the front :)

But I want more ( as we all do )
