Chrysler Sunbeam

Never say never when it comes to Mopar, BUT, if you've ever seen under the "bonnet" of a Tiger, you'd see there is NO room for a 383. The tiny 260/289/302 is a very tight fit.

Could you be thinking of the Jensen Interceptor? They came with 383's and 440's.
I am pretty sure it was a Tiger. But then again it was maybe 25 years ago, so I could be wrong.
I'll have to fish through my old photos and see if I ever took a picture of it.
