I have a  set of 95 heads to put on the car, if that would help--I am 
considering  this more or less to be able to run regular fuel, since that is 
also a  goal of mine.  If a diff/trans swap is reccommended, I would be  
willing to swap in just about anything I could trade for (preferably  keeping 
it a 4 speed).

Any ideas?  Advice is mucho  appreciated!

Tom - I would suggest a 3.27 axle as a big change - 3.08 grears are like  
finding hens teeth for a late model. You can mimic a differential change by  
trying some taller tires. It does somewhat depend on your regular driving. If  you 
do a lot of highway driving, the diff gearing makes a great difference.  
Around town, not so much.  Going to regular gas will reduce your day-to-day  cost, 
but mileage will suffer some. You will have to play with both timing and  
jetting to get the combination just right. It is a noble goal. Also, take all  
the extra weight you can out of the car. It really does make a difference. And  
make sure your tires are fully inflated, minding the front/rear  differences.
