Two words that can swing a muscle car's price by six figures.

The VIN says what the car was born with. The block casting says what's actually under the hood today. When those two stories match, that's the whole game — this is how you check, before you pay, before you sell, or just to finally know what's sitting in your own garage.

Three places to check

A car's real story is never in just one spot — it's spread across the VIN, the tags, and the engine itself.

01 / VIN

What it was born with

Year, plant, body style, and original engine — decoded straight from the factory's own coding system for your exact make and model.

02 / TAGS

Fender tag & build sheet

Paint, trim, and options — plus where to actually look for a surviving build sheet (hint: it's often still behind the rear seat).

03 / ENGINE

What's really in it now

Casting numbers, stamped ID pads, and date codes — the only way to tell if the engine under the hood is the one the car left the factory with.
