Yep speedo being off is in proportion not a set number so you definitely have different gears than you were told. Tires can also throw it off but from a truck perspective going for 29in tires to 33s on my old toyota didnt even throw the speed off that much at 65.

Sounds to me like you swapped the speedo gears for 3.23s and got another 2.73 rear end.

My condolences
