I am rebuilding a Moss Malvern ATM. Just now refurbing a Toledo 1500 TC engine for it. This is basically a Triumph Spitfire engine RWD setup. In the light of the now scarcity of Sierras these may be of interest to some who want a roadster "on a budget" Old pushrod technology I know but some of the Dolomite engines are pretty hot and later transverse engines are easily converted to RWD.
There are still quite a few about .
