I just called my friend with the Escort Rally car to get the details.
The car has a 1800cc Lotus Twin Cam. The factory used selected
blocks and overbored them to 1800cc. Not a lot were made. His car
ran the Safari the last year prior to BDAs. They had the BDAs that
year but did not use them in the Safari due to fear of bad fuel.
That is probably why they finished behind the 240Z. The car has a
ZF 5sp, Atlas LSD, is dry sumped and has 4 wheel discs. They used
lotus elan calipers in the rear with the integral parking brake.
They made very few of these models. It has the proper ID and
scrutineers tag from the Safari.

These make excellent vintage race cars. There is a very quick
1300cc Anglia I race against (basically a 1300FF motor).
