I recently inherited a 1970 T-Bird 2 Door Landau. It was my grandmothers and she left it to me. There are a handful of cosmetic things that I will do to it further down the road, but the first thing I want to do is get it running. This car has been sitting under a carport in South Texas or in a barn in Central Texas and has not been ran in at least the last 25 years. It has the 429 Thunderjet in it. I am not a mechanic by any stretch of the imagination, but have a friend who is and he will be helping me do the work. I am trying to figure out:

1: What would be the first steps to restoring the drivetrain to this car? Drain the oils? Flush them out? With what?

2: Replace all the different oils? With what?

3: What would I need to do to this engine to make it run on modern day gas? If I remember right, the gas back in the days were a lot higher octane.

4: What are some modifications I could make to the engine to improve performance? Speed, acceleration?

5: Anything in particular I would need to do to the exhaust system?

6: I was also considering eventually putting an air bag suspension on this car? Any ideas if I would need to lift the car at all for additional clearance?

Any help would be greatly appreciated. I had been after my grandmother for years to sell me this car and she never would. She ended up giving it to me instead, so I want to make sure I restore it well.

Thanks,
Jason

To run this car on unleaded gas it will need the valves and seats redone or run it it with a lead additive.
