1974 Duster Big Block

They NEVER made a big block Duster. And in 1974, you couldn't even get a big block in an E-body. Largest engine in the Duster or any other A-body or E-body in 74 was a 360. 360 was also the largest Cubic inch engine EVER in a Duster or any 70-76 A-body. So as cool as this car could be, NOT a factory big block car.

That is all besides the point that 1971 was the LAST year of the 383 anyway, in 72 and newer 400 took over as the B block
