Here’s a whole bunch of 440 engines built and supplied throughout 2017.

First up, this 440 was built for Will’s Charger, which was all set to be supercharged.

Another Charger 440 motor, this one was fully rebuilt for Tony’s 1971 R/T model.

This 440 Six Pack headed off to be fitted in a Jensen.

Finally, here’s a pair of 440 Six Packs. One is Steve’s numbers matching 1970 Barracuda 440 Six Pack, the other is its replacement.
