I'm hoping to locate a specification sheet for the Holbay 1150cc downdraft engine circa 1965/6 which is designated as the S65 race engine.

Any Holbay serviceable con rods, dry sump pumps, tacho drives or rocker covers to suit would also be of interest. (There's interchangeability with some parts from three bearing Formula Junior motors through to 1600 FF ones).

It has a downdraft head (Holbay 105E based modified Anglia) and twin downdraft Weber 40 IDF carbs. Based on a 5 bearing 120E Ford block, rope seal version is the unit I'm most interested in?



Bores 85mm and stroke 50.65mm..........
