The price reference is the median of configuration medians, not the median of all active cars. Each configuration has equal weight. Configurations with at least 3 priced listings are used when available; otherwise the reference uses the configurations with a recorded price. Model years, mileage and condition vary. Open a model-year report below for its asking prices across all engines.
Where the 14.9L 6-cyl sits in the Cascadia engine lineup
Every engine family this model was sold with, ordered by size. The bar spans the model years recorded for it; the price is a reference across priced configurations, with each configuration weighted equally. Older engines look cheaper because the cars are older — overlapping years alone do not match the vehicles by age, trim, mileage or condition.

Which Cascadia years got a 14.9L 6-cyl engine
Every model year this engine was fitted to, newest first. The bar is how much of the family's VIN volume sits in that year — long bars are the years this engine was everywhere.
VIN counts come from our decode of the model's build patterns, not from live listings. A year link opens the full Cascadia report for that year — every engine of the model, not just this one.

Each one is a distinct build as the VIN decodes it — trim, body, gearbox and equipment. Open a build sheet for its full spec and the VINs recorded on it.

Which Cascadia years have the 14.9L 6-cyl?
2010–2017, without a break — 8 model years in our VIN decode, across 21 factory configurations and 2,216 VINs.
What does a 14.9L 6-cyl Cascadia cost?
$23,895 is a configuration price reference: the median of configuration medians, with each priced configuration weighted equally. It is not a listing-level median or a valuation of an individual car. The year-by-year ladder shows VIN and inventory counts; its links open model-year price reports covering all engines.
What is the engine code, and does it matter?
Cummins ISX — the code the VIN decodes to on the configurations on this page. It matters when you order parts or read a service history: the same displacement badge on another model can be a different code with different outputs.
