383 Build up questions...

Let me ask you, is there a "ET" you wish it to be able to perform?

Basic "Hot Rod" principals apply here.
The cam your use will need to perform in the RPM range you want it too.

In general, a basic build could be as easy as;

750 carb
RPM intake
Pocket ported heads.
(A smaller vale size in a 383 isn't a bad thing. If your OE valves are 2.08's, it is possible to use these to a great advantage. See BJRracing for tips and tricks)
Standard tube size headers are OK fine for "General useage"
Upgrade the tranny and slip in a set of gears onthe car and you'll roast the crap out of the tires with a sneeze.
