Is Dodge 400 a big block?

The Dodge 400 is not considered a big block engine. It is actually classified as a small block engine. The Dodge 400 is a member of the B-series of V-8 engines produced by Chrysler, Dodge, and Plymouth. It was introduced in 1972 as a response to new smog control legislation and was essentially a bored-out version of the 383 engine.
The 400-cubic inch engine was available in both high-performance and standard versions. It had a bore and stroke of 4.34 inches by 3.38 inches and a compression ratio of 8.2-to-1. The last big block Chrysler engine was produced in August 1978, and the 400 was still standard in the 1978 Chrysler Newport and New Yorker.
While the Dodge 400 is not a big block engine, it is still a popular choice among enthusiasts for its strong engine blocks, low deck design, and great rod ratio. It can be modified to boost power and improve fuel efficiency.
