An unrestored 1968 Chevy Impala that had been stored for years is now back with a strange engine.

A lot of things are unknown about the 1968 Chevy Impala because it was one of the most powerful cars of its time. But not many Impalas have kept their power,

and even fewer have gained it. In one case, this Impala was put away for years and is now back with a strange engine.  

Tom Jones bought the car from his uncle, who had kept it in a barn for many years.

When he started to fix up the car, he found that the engine wasn't the original.  

There was no 427-cubic-inch V8 engine for the Impala in 1968, but this one did.  

Tom has no idea how or where the engine got into the car.
