Just one thought, how original/complete is the car? It sounds like a factory V8 (assuming station wagon, haven't seen any photos).
Prices for completely standard factory V8s are some of the highest (accounting for age and mileage) so before making anything too permanent, you might want to consider ways forward. They're not quite collectors items yet, but the more that get modified, the closer we get.
I'm all for doing what you want with your own car, but I try not too think about how much value I wiped off mine.
