Geez NormK why would anyone entertain such an idea and actually carry it out? They were not known for low end performance and they put it in a heavy car.
Reminds me of the HJ Kingswoods badged as Mazdas, exported to Japan and fitted with rotaries.
At least the Kingswood taxicabs I remember fitted with four pot Peugeot diesel engines would have had low down grunt.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
