70 duster project

I’m definitely going to drive the car, mostly weekends. Pretty rural around here, more 60 70 mph than stop light to stop light. I’d also like to take it to the track for test and tune just for fun, using the flowmasters because I already have them. Probly get a set of cut outs to. Trying to make the most of what I have without buying a bunch of parts. I know horse power cast money. And toys cost money, and having fun in general cost money, But if I can make a lot of fun on a budget that would be better. I have to buy a set of gears, probly a cam. Obviously a rebuild kit. Which could include pistons. I’ve been looking at a lot of threads on here, trying to figure out my best combination, it’s an on going thought process with everything I learn
