Triumph Herald 1200 V8

We particularly enjoy a good conversion. Getting a non standard engine or gearbox etc to fit right, work right and look right can be tricky but very satisfying. I have already converted a couple of Spitfires to Rover V8 power very succesfully. So a Herald should be a breeze with having the extra bonnet height.

Below is Andy Plews' 1200 before and after.   We just had to assemble a power unit and install it, the rest is up to him!


First trial fit to highlight major areas for surgery. A piece of bulkhead each side to clear the heads, some chassis trimming around the gearbox, some pieces of gearbox itself and mountings to create.


Fitted and refitted about a dozen times to get it just right. Sitting nicely back with enough room for radiator. Sump clears steering rack and crossmember well. Exhausts are always a problem with none of the factory right hand side manifolds suitable.


Bonnet and front valance on. TR6 radiator should be up to the job. Neat bonnet 'scoop' echos the wing top profiles and provides the necessary clearance for the SU carbs. A Holley or Weber 4 barrel downdraft carb on a suitable manifold would have gone under the bonnet with no modifications, but the cost persuaded the owner to choose the scoop instead.  Looks swish in Glacier White, the rest is up to you Andy.


Well, not it is some months later after completing the Round Britain Reliability Run. (2000 miles in a weekend!) We had much more to do on it before it was roadworthy including getting the engine connected up, exhaust, cooling, electrics, suspension, brakes, hood and frame and the final MOT preparations. One piece custom grille made from stainless mesh powder coated black gives the front a clean look. Wheels are MGF 15"on M12 studs.  


After a short spell with a 'long' SD1 water pump as shown in the first pictures we converted to a short set up. Primarily to give room for a proper electric fan. Although there is much more height under the Herald bonnet compared to a Spitfire. The issue became length with, as you can see, minimal clearance for water pump pulley to fan. Car runs cool though, and ridiculously quick for an old Herald.
