|1967 Ferrari 330 GTC (Serial # 10255)
I am pleased to report that we have now completed all of the machine work for this project and rebuilt/assembled both cylinder heads.
|Honing rod wrist pin bushings to size
||Hanging rebuilt rods on the pistons
|Torque plate honing the cylinders to final
||Pressure testing with custom head gaskets
|Balancing the flywheel and clutch
||Assembling the cylinder head and setting
|Heads now full rebuilt and ready to install
We have now received your custom forged pistons. It's always fun to see the finished product when so much work has gone into the design and production behind the scenes.
Corey has been busy designing and machining a piston mold from which a new set of custom forged pistons will be made.

needed align hone
|Setting up for align hone with cylinder
bolted in place beneath block (essential)
|Magnaflux checking rods
||Honing rod housings

Damaged oil pan spends a little time with Jake in the CJ Coachworks...
|Weighing connecting rods after cleaning
||Ferrari rods of the era had the weight
on them - in this case 514g
|Complex timing chain idler sprocket
||Water pump bearings and gear badly worn
|Timing gear idler assembly

|Repaired pan looking virtually new once
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
|No to valve jobs were the same!
|This line clearly visible on the bottom
evidence of coil bind
|Pressure testing cylinder heads
|This cylinder had .009" skirt clearance!
||Knurled piston is cost saving old school
|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
||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
|Panel has slight damage around transmission
mound that will be repaired
|Framework of the dash exposed
|Hundreds of rivets hold the floor pan and
and rear bulkheads in place
|Panel beneath rear window is aluminium
|Removing rear window panel/upper rear
|Rear panel now removed
|Main floor pan now lifted away
|Removing pans was essential to gain full
to the chassis
|Many rivets were broken or corroded
|Chassis will be blasted back to bare metal,
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
V12 from the engine bay
|Engine is angled in order to clear the
on the way out
|With the engine on the ground, the
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
|Left rear strut mount
||Right rear strut mount slightly damaged and
upward, causing car to ride low in right rear
|Strange assortment lurking beneath gas
||Unspent shotgun cartridges, Italian
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
|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
|Some photos are for reference purposes only
|Jake and Carlos double teaming the front
One last inspection by the proud owner before we get this project underway!
|One last opportunity for the proud owner to
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!
