I don't think it's homologatrd. We were running 1380 and 1399 in the late 70s and early 80s and I have no reason to believe that it was a new idea even then. I even tried a long stroke 1380 which was something like 1460 (????? I can't remember) but kept burning pistons out around the original Combe.
AFAIK the only homologation it carries is Goodwood's!
