How much does a 1974 Chevy dump truck weigh?

Please give a specific model. The dump bodies and hydraulic system will be aftermarket, but you there's no way to tell you anything if we don't know whether you're talking about a 1/2 ton C/K pickup or one of the Class 8 trucks Chevrolet manufactured at the time (Chevrolet exited that market in 1980; GMC followed suit when their heavy truck division was bought out by A.B. Volvo in 1988).
