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.

Where the 5.7L 8-cyl sits in the Sierra 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.
1989–1999 The 5.0L 8-cyl configuration price reference is about $11,495 less — $6,500 against $17,995. These references cover each family's full set of priced configurations; they are not recalculated for the overlapping years or matched cars.

Which Sierra years got a 5.7L 8-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 Sierra report for that year — every engine of the model, not just this one.

The 5.7L 8-cyl Sierra: common questions
Which Sierra years have the 5.7L 8-cyl?
1989–2000, without a break — 12 model years in our VIN decode, across 91 factory configurations and 9,162 VINs.
What does a 5.7L 8-cyl Sierra cost?
$17,995 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?
L31 — 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.
