There is a 1958 GMC 100 for sale locally, and the owner says it has "the original" 235 in it. My first reaction was "that's a Chevy engine, not a GMC engine." The research I have done suggests that GMC sixes in 1958 were 248's or bigger. I also know they installed V-8's from other GM divisions, such as Pontiac. Does anyone know whether GMC factory installed chevy 235's in 1958?
