1966 Chevelle SS

Not sure which car you bought?

If it's believed or was sold as numbers matching meaning original drivetrain, I hope you verified that before buying but no, the VIN tells you nothing of the original engine that would have come in the car. The engine deck stamp will tell you what the Hp rating is. Again if the original engine is in fact in the car now. If it's not, only factory docs will tell you whether it was the base 396/325hp or the optional 396/360hp. Doubt it's the 396/375hp of which only 3099 were released.

The suffix code on the deck stamp will tell you whether it's 325 or 360. ED EDH EF etc. but you can't rely on that as FACT. Lots of restamps out there and knowing what the deck stamp for your car's assembly plant at the time your car was assembled ( engine ) plays into this as well. Each plant did things differently. Too many people just LOOK to see if the deck stamp MATCHES the VIN TAG. Plus the vin will be stamped on the transmission too if it was supposed to be original drivetrain.

Enjoy your car no matter what and post some pics
