454 Medium Duty V-8

[ClassicTVMan1981X]

How many of you here own a 1979-80 Chevrolet C70 or GMC C7000 with the rare, tall-deck 454 V-8 engine?

This engine was not used in the mediums from 1981 to 1998, but it would return for 1999 as the "Vortec 7400 MD" to replace the ubiquitous 366 and 427 big block V-8s in the then-current C and T series. In 2002, it was replaced by the Vortec 8100 MD engine, which lasted through the early part of the 2010 model year.
