The most aggressive of our CH383 combinations packs the wallop of a big block in small block dimensions. Usually you will see these numbers associated with larger cubic inch small blocks. Why? Crate engine assemblers will not take the time or have the ability to extract the full potential from a combination. We have put in the time, and created the true 383 “Anti-Crate” for any high performance enthusiast.
