When did the Chevy 400 engine come out?

by Moss Strohem. The 400 CID Chevy small block engine was produced from 1970 until 1980 and was the largest displacement engine made in that platform. It was intended as a low performance, high-torque engine primarily used in Chevy’s heavier passenger cars and light-duty trucks.

What’s the difference between a 350 and 400 engine Chevy?

Introduced in the mid 1950s, the small block Chevy (SBC) used a standard V-8 engine block design that was physically smaller and lighter than the Chevy big block engines. They have been built in different displacements ranging from 262 to 400 cubic inches. Both the 350 and 400 cubic inch engines are SBCs.

How did the Chevy 400 get the extra displacement?

GM had to cast the block for the 400 CID engine differently to gain the extra displacement. To gain the extra 1/8-inch bore diameter, the cooling system water jackets between adjacent cylinders were eliminated on the 400 block.

What are the dimensions of a Chevy 400?

Physical Dimensions. The engine shares the same length, width and height as other SBCs at approximately 28 by 26 by 27 inches respectively. The identical external measurements made the 400 SBC readily interchangeable with other Chevy engines, such as the 350 CID small block engine, across many of the Chevy and GMC truck and Chevrolet car lines.

What’s the difference between a 400 and 350 Block Chevy?

GM had to cast the block for the 400 CID engine differently to gain the extra displacement. To gain the extra 1/8-inch bore diameter, the cooling system water jackets between adjacent cylinders were eliminated on the 400 block. Additionally, GM designed the 400 crankshaft with larger main journals than the 350 – 2.65 inches versus 2.45 inches.
