Tall gears and 4-speeds

I recently bought a duster (3300ish) has a mild 318, 833, 2.76, and 26” tires. It drives pretty nice, about 1800@55mph, great if nice is what your looking for. It will move pretty good if you get the r’s up, but just doesn’t have what you expect out of a 70’s muscle car, I’m definitely going 3.55 or 3.91
