This nitrous-fed 632ci BBC "Mudder" came in for a refresh. Heading into its sixth season, this engine has withstood a lot over the years and is now ready for a lot more.

Designed to run race fuel, you won't be seeing this guy on the street. It's a dedicated mud racing bottle-baby. Nitrous bottle that is. The 632 cubic inch displacement comes from the 4.6"bore of the Dart Big M block and 4.75" stroke of its Callies Magnum crank.

We did not spray during this dyno session and the owner has asked that we not release any data. Turn up the volume, make sure the subwoofer is working and enjoy the look and sound of Big Block Chevy power!
