If your shop is mopar literate he should now how to do it.If they are not you will have to be specific with what you want and how to get there.A true 9.5-1 with iron heads is about max for pump gas.Any money spent on porting the heads(knowledgeable porting work that is)is well spent.Most of your power gains will come from here.
The lunati voodoo cam 60302 would be a good street cam with the 3.23's.Maybe the 60303 with the 3.91's as long as you have a true 9.5-1.A performer rpm or dp4b intake,a 700dp(or 750 vacuum holley),1 3/4 headers,and a 2600-2800 stall converter will wake that thing up.Make sure you have your dist recurved or just use the mp electronic one to get your advance in sooner.Running more initial advance will help with the idle and throttle response as well.
