I recall at least 413 cubic inches while other models had Hemi-head engines.

This one looks like a 413 with that dual cross-over manifold with twin 4 barrel carbs.

Update: My brother-in-law Joe Gibbs reminded me via Facebook that the name for that intake manifold system was "Ram Induction." I think he's right.

That trunk is huge!

This is a radical custom of a Chrysler Imperial.

For the record, Imperial as a marque was always sold in Chrysler dealerships and never in distinct Imperial dealerships. So, the nameplate failed to separate itself as its own marque as a consequence.

This custom version retains the width but with a much shorter wheelbase. It caught everyone's eye when it drove in on set-up night of the Detroit Autorama 2011.

Detroit Autorama 2011 brings out the best in modifications, such as this extremely shortened body of a Chrysler Imperial.
