Why Buy a 2020 Chevy Silverado 1500 Engine from Auto Power Source
Every 2020 Silverado 1500 engine we list is inventory-verified against its donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Our ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before any unit is cleared for sale.
The 2020 Silverado 1500 stocks five displacements — 2.7L (opt L3B), 3.0L (opt LM2), 4.3L (opt LV3), 5.3L (opt L82 and opt L84) and 6.2L (opt L87) — and the 5.3L is cataloged under two option codes carrying different 8th-digit VIN codes, so the option code and the VIN digit both have to line up. Text your VIN and we will confirm the exact match before you order.

2020 Silverado 1500 Engine Buying Guide
-
Confirm the 8th-digit VIN code. The 2020 Silverado 1500 2.7L ships under VIN K, the 3.0L under VIN T, the 4.3L under VIN H and the 6.2L under VIN L, while the two 5.3L builds ship under VIN F (opt L82) and VIN D (opt L84) — the 8th digit is what separates them.
-
Match the engine option code. Our 2.7L units are opt L3B, the 3.0L opt LM2, the 4.3L opt LV3 and the 6.2L opt L87, while the 5.3L is stocked as both opt L82 and opt L84; the option code is cataloged on every listing.
-
Separate the two 5.3L builds. Our 5.3L is stocked as opt L82 (VIN F, 8th digit) and opt L84 (VIN D, 8th digit); we catalog each fitment separately.
-
Check brackets and ancillaries. Accessory mounting and sensor harnesses can differ between fitments — tell us what came off the truck.
-
Always run the donor VIN if available. We provide it on request for any Silverado 1500 engine in inventory to verify mileage and history.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
