GMC Sprint

GMC Sprint

The GMC Sprint was freshly redesigned for 1973, along its cousin the Chevrolet Elcamino. The hot Sprint to have was the Sprint SP. The SP added rally wheels, side stripe with ‘SP’, and a tighter suspension. Let’s not forget the 454 CID LS4 V8 that the SP had. It was rated at 245hp. The engine lineup for the rest of the Sprints were a 250 1bbl I6, 307 2bbl V8, 350 2bbl V8, 350 4bbl V8. For 1974, the 307 was dropped and added were a 400 2bbl V8 and 400 4bbl V8. For 1975, the 400 2bbl was dropped, plus all Sprints got catalytic converters. By this time, the 454 was down in power as well, and ’75 was the last year for it in the Sprint.

For 1976, the Sprint lineup received stacked rectangular headlamps. A 305 2bbl V8 was added to the selection of engines, and of course the 454 was already gone. The Sprint SP lived through each of these years but as the larger engines were phased out, the SP became a little more watered down each model year. The 350 2bbl and 400 4bbl were both dropped for 1977. It was also the last model year for the Sprint nameplate, as it was replaced by the Caballero the next year.
