Where the 4.3L 6-cyl sits in the Sierra engine lineup
Every engine family this model was sold with, ordered by size. The bar spans the model years it was fitted; the price is what cars carrying it ask today. Older engines look cheaper because the cars are older — the only fair comparison is an engine whose years overlap this one's.

Which Sierra years got a 4.3L 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 Sierra report for that year — every engine of the model, not just this one.

The 4.3L 6-cyl Sierra: common questions
Which Sierra years have the 4.3L 6-cyl?
1989–2021, without a break — 33 model years in our VIN decode, across 145 factory configurations and 36,557 VINs.
What does a 4.3L 6-cyl Sierra cost?
$15,999 is the typical asking price across the 530 cars with this engine on sale today. The year-by-year ladder above splits that by model year — the spread between the oldest and newest year is far wider than the spread between engines.
What is the engine code, and does it matter?
LV3 - VVT, Aluminum, E85 Max — 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.
