Did Chevy make a 400 engine?

Yes, Chevrolet did make a 400 engine. There are two different engines referred to as the “400” in the context of Chevrolet:
1. Chevrolet 400: The Chevrolet 400 was a compact car made by General Motors de Argentina from 1962 to 1974. It was based on the Chevrolet model known in the United States as the Chevy II or Chevrolet Nova. Only the 4-door sedan version was manufactured in Argentina, while the U.S. versions included a complete line of body styles, including a hardtop coupe, convertible coupe, 2-door sedan, and station wagon.
2. Small Block Chevy 400: The Small Block Chevy 400 is a V8 engine that was produced by General Motors. It was intended as a low-performance, high-torque engine primarily used in Chevy’s heavier passenger cars and light-duty trucks. The 400 has gained notoriety with modifications as a powerful performance engine. It shares many external features and dimensions with earlier small block Chevrolet engines but has internal differences. The 400 SBC engine has a displacement of just over 400.9 cubic inches, achieved by increasing the bore to 4.125 inches and the crankshaft stroke to 3.75 inches.
So, to summarize, Chevrolet made the Chevrolet 400 in Argentina and the Small Block Chevy 400 as a V8 engine for their vehicles.

The 400 small block uses the same block as the 350 but the cylinders are bored out another 1/8″.

A 400 SBC is a fine performance engine (in my opinion), and is no stronger or weaker than a stock 350 block. A 350 block is a 4″ bore and can be bored safetly to 4.03″ but some people go higher. If you sonic check the block you may be able to bore it more.
