Jensen CV8 Engine-Bays
The quest for originality can be demanding, particularly when correct detail is important. One feature of a Jensen which takes time and expertise to get just right, is the engine-bay. Many decades have elapsed since the cars were first built, and in that time all manner of detail may have been changed. The engine-bay of the Jensen CV8 incorporated various changes during the evolution of the model from MK.I through to MK.III. The Museum looks at the detail of a Jensen CV8 engine-bay.

Jensen CV8 engine-bay MK.I
Overview of the CV8 MK.I engine bay
The Chrysler 5.9 litre 361cu in V8 ‘Golden Commando’ engine was fitted to the CV8. The engine came over from Chrysler to Jensen Motors painted in Chrysler torquise. Once at Jensen, they stripped off all the ancillaries, and sprayed the engine black. The engine had a Carter AFB carburetter. A large metal silver finished air-can with twin snorkels sat on the carburetter’s top.
The braking system includes a Lockheed servo, along with Dunlop dual piston calipers. As much as this system was praised in its day by Autocar testers, they did put in the caveat that they would have preferred independant hydraulic circuits for front and rear braking. It took until the launch of the MK.III before Jensen did precisely that.
Jensen CV8 engine-bay MK.II
Overview of the CV8 MK.II
In January 1964, a larger capacity engine was fitted to the CV8. Chrysler’s 6.3 litre 383 cu in V8 would take over from their 361 cu in engine.The 383 engine had a larger bore size and a higher performance camshaft. As with the 361 engine, they came over from Chrysler to Jensen Motors painted in Chrysler torquise paint. Jensen stripped off all the ancilaries and sprayed them black. With the Mk.II, and the fitting of the 383 engine, a change of air-can took place. Now it was a metal air-can painted in black, and with a single circular snorkle. Of note is the fact that this air-can did not have a breather pipe attached from the air-can to the rocker-cover.
Jensen CV8 engine-bay MK.III
Overview of the CV8 MK.III
Chrysler’s 383 cu in V8 continued to be fitted to the new CV8 Mk.III. A Smith’s fan motor potruded from the centre of the bulkhead to improve interior heat and ventilation. As a result the main relay box was moved to one side of the motor.
The Lockheed servo was now discarded in favour of the Dunlop servo and master-cylinder, with a seperated back and front system. The single brake reservoir tin was also now discarded for two white plastic brake reservoirs. The black finished air-can now had a rubber breather pipe across to the left-hand rocker-cover.
