Hi; As far as I know the last Hemi equipped Imperials left the factory in 1958, how many of those were fitted with 392's built to Chrysler 300 specs is unknown. There is a common misconception with the early Hemis that the 300's had just a regular Hemi with a dual quad manifold on top but they were actually a race engine almost as much as the 426. As for the Imperials of the later 60's I would very much doubt it, the type of buyer that these cars attracted were usually wealthy order people who wouldn't know Richard Petty from Gloria Vanderbilt's gardener. The 426 Hemi is a race engine, noisy, rough running, violent, and high maintenance, all of the things that a 440 is not. On the other hand I wouldn't sell the 440 engines short when it comes to power, they have more then enough to move these cars around, even the detuned ones from the 70's. As powerful as the 426's are they were never designed for low RPM torque to move a 7000+ pound car around, in that respect the performance gain would be negligible. The 440, even in the Plymouth and Dodge cars, was never developed to its full potential for performance by Chrysler as they had it in the bag with the 426 Hemi, but it is still a well designed engine capable of making lots of power with minimum upgrades. Most of the cop cars that Chrysler sold in the 60's and 70's used 440's and that was in the muscle car era. If Chrysler had taken the same path with this engine that they had with the earlier 413s we wouldn't be having this discussion.

Back in the 60's car companies were willing to build a car according to the purchaser's wishes-to some extent, has there ever been any Imperial fitted with a 426 Hemi engine from the factory?, or has someone out there modified an Imperial in such a way?, it would be an awsome sight if done properly to look like a factory job, not to mention the improved performance. Chrysler lost the edge to Dodge/Plymouth when it came to specialty cars once the Letter series 300s were shelved, would have been the ultimate Imperial!
