1958 XK 150 roadster (JB) Major mechanical overhaul

Specification (briefly) for this project is as follows: This is a nice, presentable XK that we are going to mechanically upgrade from stem to stern. The car will receive uprated Team CJ cooling, ignition, braking, suspension, a Stage One E Type engine, triple SU carbs and a CJ5 five speed transmission. The finished article will be the proverbial wolf in sheep's clothing!

We now have the cylinder head completely rebuilt and installed and have started installing all the other engine bay ancillaries, such as the new Mallory distributor, spin-on oil filter and of course the polished stainless steel headers. We should have the old car back on the road in the next week or so.

Modified cam/tach drive worked out perfectly	Lifting hooks added for  convenience	Polished valve covers add the finishing touch
Headers installed	Note new mallory distributor and modern oil filter	Rebuilt carbs squeezed into place

Although we are not quite finished with the cylinder head yet, we went ahead and rebuilt the block and installed it in the car, along with your new CJ5 five speed. We have also completed the carb rebuild.

With the new engine sleeves installed, the following photos show the new cylinders being finish honed.

We have been steadily gathering  various new components while we wait for the engine machine work to be completed.....

Some of the new components going into your cylinder head rebuild	Beautiful new aluminum radiator
Polished SS headers will provide the sounds....	New HP stainless exhausts

The first photograph below (scanned from Philip Porter's excellent "Original XK" book) shows how the factory cut away the right hand engine bay sidewall to make room for the triple carbs used on the 'S' models. The next photographs show your car, before and after the same side panel has been removed.

With the front suspension rebuild completed, we have now installed the upgraded brake booster and the new Koni shock absorbers at the rear of the car. We have also received most of the carb parts back from the polishing shop.

Your original suspension was in a terrible state and required a complete rebuild, including new shocks, torsion bars, Poly bushings, upper and lower balljoints, wheel bearings, etc, etc.
