What is a Dodge build sheet?

A build sheet is the factory's own record of how one specific vehicle was assembled. For a Dodge it lists every sales code — engine, transmission, axle, paint, packages, and options — tied to the VIN.

It's the most reliable way to confirm how a used Charger, Challenger, or Durango was originally configured — far more dependable than a badge or a listing.

What the build sheet shows

Powertrain, trim, exterior and interior colors, wheels, option packages, and dealer-installed-at-factory equipment — the details that explain why two cars with the same model name can feel completely different.

On performance models it separates the genuine hardware — Scat Pack, SRT, Hellcat equipment — from appearance packages that only look the part.

Sales codes explained

Stellantis / FCA vehicles use 3-character factory sales codes on the build sheet. One package code can bundle several smaller features, so reading the sheet carefully tells you what the car actually carries.

Factory data is the baseline, not proof of current condition — wheels, audio, and trim may have changed since delivery, so use the sheet alongside photos and an inspection.

Can VIN data identify an engine swap?

Considering a cheap 2010 Challenger as a second project car, and something under the hood does not smell right, figuratively. Listing says one engine, a couple of stickers say another, and the seller's story has already changed once. I know the VIN records what the car was born with. Can VIN data actually identify an engine swap, in the sense of proving the current engine is not original? Or does it only tell me the birth engine and leave the detective work about the present one to me?

The latter. VIN and factory record prove the born-with engine only. To detect a swap you compare that answer against the physical engine: displacement, casting features, accessory layout. The paper gives you the reference truth, your eyes supply the mismatch.

Practical shortcut: decode the eighth VIN character, then check whether the engine cover, intake, and exhaust manifolds match that engine family. A swap that survives that comparison was done by someone thorough, which honestly tells you something too.

Changed stories plus mismatched stickers would send me straight to the record before the second viewing. If the paper and the bay disagree, price it as a swap and demand receipts for the work.

Decoded it: born a V6, wearing 5.7 badges and, per the seller, now a mystery. Walking away from this one. Thanks for the sanity check, team.
