Of course, Ford was introducing a new big block, the 332/352 FE series, Chryco was introducing a new 350 cubic inch engine in the Plymouth, and Chevy had to use a "truck" engine in THEIR cars?. Like they didn't have passenger cars in mind FROM THE START?. Like what the other manufacturers were doing were a big dark secret?. When they say the W block was used it was because they didn't have anything else?. They didn't KNOW that the new 1958 HAD to have a big block when the began designing it, as early as 1955/56?.
Chevrolet engineers began calling the W block a "truck" engine from the start of production, WHY?. 3 engines being examined for use in the new bigger cars then on the drawing boards. 2 were based on the small block, the 3rd was the W block. When that engine was chosen they began developing a full line of engines, FOR PASSENGER CARS!. Records prove that by 1956 the W was chosen for PASSENGER cars, very FEW for trucks.
Yet the Chevrolet engineers called it a TRUCK engine, told all the auto magazine writers it was a "truck" engine, not the other way around. And it's STILL being called a truck engine today!. Why?. There's your question for today, why did they call it a truck engine?. The label has stuck, it will always be connected to the W.
And the 409 wasn't put in the Corvette because the 327 could put out nearly the same horsepower and weighed 150 lbs less. They didn't TORQUE, or that weight over the front wheels. Besides which, with Duntov designing the W engine (at least the heads) some engineers told him "Zora, don't even THINK about it!).
