We know from service records that this engine had been rebuilt back in the 1980s and has been driven very few miles since. Unfortunately, the quality of the rebuild leaves much to be desired, and we therefore have a full rebuild underway.

Inappropriate valve springs were used, resulting in coil bind, the valve stem to guide clearances are huge (over .004"), and piston skirt clearances range anywhere from .004" to .009". One of the most telling signs that this car did not receive the engine rebuild it deserved was the presence of a knurled piston. Knurling pistons is an old school practice designed to give extended life to worn pistons. Knurling a piston skirt actually helps 'take up the slack' in the case of loose skirt clearance, but the high spots created by the knurling process wear very quickly, so the remedy is very short lived.
Despite the use of the knurled piston, the skirt clearance in that particular cylinder was .009", or .005" out of spec.




Disassembling the cylinder heads











All the valve seats had different widths
and heights
No to valve jobs were the same!






















This line clearly visible on the bottom coil is
evidence of coil bind
Pressure testing cylinder heads










This cylinder had .009" skirt clearance!
Knurled piston is cost saving old school
practice










Stem to guide clearances were huge
Valve stems measured inconsistently





Engine tear down underway in the CJ machine shop.
















Strong fuel smell in oil pan


































First head removed











Amazingly slimline V12 block
Signs of fuel wash and scuffing on pistons
and cylinder bores




I was very pleased to come across the very first Ferrari 330 GTC prototype on display in Las Vegas last week. Chassis number 6431 was originally built on a 275 GTS chassis and was apparently regularly used by Enzo Ferrari himself. The car has dozens of detail features not seen on any other 330 GTC.



Koni have done a stellar job rebuilding
your original shocks
The prototype Ferrari 330GTC






We have now received the restored fuse board and superb quality wiring harness that was made for us in Italy. It really is a very impressive piece of kit.




The original fuse panels have been restored
and completely rewired












Every terminal has been carefully labeled




Front suspension rebuild underway - and some beautifully restored Borrani wire wheels...



Suspension and brakes will be completely rebuilt
Separating the springs and shocks










Road springs will be replaced, Koni shocks
will be rebuilt at the Koni factory
























The Borrani factory in Milan have done
a fantastic job with your wheels!




Back from being media blasted to back to bare metal, a few minor rust issues are exposed, and also evidence of some sub-standard 1960's Italian bodywork.













































































































































Preparing the Ferrari for blasting back to bare metal..






















Removing the fiberglass dash and floor pan in order to gain full access to the chassis..



Fiberglass dash/firewall is first to be removed











Panel has slight damage around transmission
mound that will be repaired
Framework of the dash exposed






















Hundreds of rivets hold the floor pan and front
and rear bulkheads in place
Panel beneath rear window is aluminium











Removing rear window panel/upper rear bulkhead























Rear panel now removed











Main floor pan now lifted away










Removing pans was essential to gain full access
to the chassis
Many rivets were broken or corroded










Chassis will be blasted back to bare metal, repaired
and refinished to new condition











Unusual view from beneath the car with the
floor pans removed






Time to remove the engine and gearbox...



Lowering the 5 speed gearbox to the ground
With the gearbox out of the way, removal of
the engine is a simple matter










Chris Scarborough carefully extracting the compact
V12 from the engine bay
Engine is angled in order to clear the firewall
on the way out











Almost clear...











With the engine on the ground, the mechanical
tear down is almost complete




Tear down continued, a glittering new Borrani wheel, and unspent shotgun cartridges hidden beneath the gas tanks...




Front suspension now removed











Removing rear suspension
























Note thick bondo lurking behind front bumper










Left rear strut mount
Right rear strut mount slightly damaged and pushed
upward, causing car to ride low in right rear










Strange assortment lurking beneath gas tanks
Unspent shotgun cartridges, Italian newspaper
clipping, glue, lipsalve and screwdriver











Glittering new RW 4039 Borrani spare wheel




Tear down, continued...























































































































































































The only significant rust so far..























Drain hole in left bumper tube requires minor
rust repair












Next task is to remove the rear suspension




I am pleased to report that this important restoration is now officially underway!



First task is to remove all the glass and interior












Some photos are for reference purposes only







































































Jake and Carlos double teaming the front
windscreen removal








































One last inspection by the proud owner before we get this project underway!



One last opportunity for the proud owner to see the
car whole before the restoration gets underway

















































































































I am delighted to report that your car is safely inside the Team CJ workshops and we will have this exciting restoration underway very shortly!
