What is your budget?
Then:
What is your goal?
And:
Doing the work yourself or paying to have it done?
Answers those questions and others will be able to give you a decent answer. If you budget for great heads, modern design cam, and a 383 stroker kit you'll still need a new oil pump, want a new water pump, LS6 or bigger intake, all gaskets, pushrods, new lifters and rocker arms if you can't re-use stock ones, etc etc. Factor in a power adder and the mods to hold and put down that power and you're probably better off buying a built car unless you have a bank account that can support dropping $20k or more on your "old" car. At that point you still won't have fresh paint and interior or whatever else the car may need.
Just trying to be realistic with you. If you don't sit down and price / add up every mod that you plan on doing you'll be far from realizing what the total cost is.
