Cannot decide on project direction 73 Duster 340

My suggestion would be to do what needs to be done to make it fun to drive. Whatever that means for you.

For me, that means at least stop, ride and handle like a newer car (for now). Currently, my Duster feels on par (to me) to the R/T Challenger I just sold, minus the creature comforts and better power and mileage. But it still needs longer legs (want to cruise through MT at 80-85 mph), AC and EFI. Oh, and more power someday.

Point is, if you build it so it is fun to drive and doesn’t feel like punishment, you will drive it and enjoy it more. If it has a narrow focus and only fun for a short time, it will get left at home when you want to just enjoy the drive.

My formula would be 1.03 TB’s, 1 1/8” SB, RCD’s, 11.75” disks, subframe connectors, 3.23 or 3.55 gears with a OD box. If you wanted to keep the old school look, put some body color 15” steel wheels on it with some old school rubber. If you wanted modern tires, find some 17” wheels you like (there are even some solid ones that look like old school steel wheels) and run those. Oh and either aftermarket UCA’s or offset bushings so you can get a more modern alignment spec. Really nothing exotic or unreversable, and should be plenty fun and keep up with most of the cars on the road now.
