Apoligies if this belongs in the technical section, the questions are mainly historical.
Acquired Chris Rees book - "The Complete Catalogue of the Mini" a while back and am interested in finding out more about the 1973 Mini Clubman wide-body proposal on page 196.
Is it known how the wide-body Clubman prototype's width compares to the regular Mini Clubman, additionally is there a connection with the wide-body Clubman to rumored E-Series powered Clubman prototypes being tested by BL that were allegedly derived from a shortened Allegro platform to cut costs (unless that refers to the early ADO88 project)?
Also have recently read of the fiberglass Chilean Minis using a 750 version of the A-Series for tax reasons, which was based on the 850 yet seemingly featured the same 58mm bore from the original 803 A-Series (creating a displacement of around 721cc) and was wondering whether it is known if there was any loss over power on the 750 compared to the existing 850 engines?
