There have been three different d.o.h.c motors fitted to the rear-wheel-drive
Escorts. The first was the Lotus "Twin-Cam", using a Ford 1500 block, Lotus
head with 2 valves/cyl, size 1558cc. The car was known as the Escort Twin-Cam.
The second was the Escort RS1600, with Ford 1600 block, and Cosworth Four valve
head - the whole engine was known as the Cosworth BDA (Belt Drive, Series "A").
The rated capacity was 1601cc, but exactly the same dimensions were used for
the 1600 Mexico (push-rod) which was rated as 1599cc. Just a racing category
fiddl^H^H^H^H^H adjustment. The third motor was an aluminium block & head
from Cosworth at 1800cc. Not too sure of the designation, but it could have
been BDE. This was the RS1800, which memory says was only a MkII, not a MkI
model.
So what is the Safari car? It should have 4 valves if it's a straight line
RS1800 and the only 2 valve twin cam head fitted to those Ford blocks was
the Lotus as far as I can remember.

The original spelling of brake (as in waggon), was "break", because it was used
to tow horses behind it during the process of breaking them in.
I _could_ tell you the differences between convertible, roadster and d.h.c., but
don't fancy being flamed as a smartarse, so I won't. ;=)
