1965 Lamborghini 350 GT

Major mechanical overhaul and minor cosmetic restoration work.



Update report - April 22, 2020

We have spent literally months fine tuning the appearance of the engine bay in this Lamborghini 350 GT. It now looks very much like it would have done when the car was built in 1965.

Update report - December 24, 2019
We have been busy correcting a few points of originality in the engine bay. We still have a couple of minor items to take care of, but our 350 engine bay now looks very much like it would have done in 1965.

NOS Lucas coils, new expansion tank cap, relocated
relays, refinished air cleaner boxes and reservoirs

Bonnet strikers were previously black, now
chrome plated
Fuel filter bowl now has correct FIAAM screen
printed logo

Brake reservoirs had originally been painted black,
now cad plated per original
Master cylinders have also been refinished and new
brake lines fabricated and installed

A very proud and happy owner!

What a glorious day it was at Concorso Italiano in Monterey yesterday! The sun shone down on 1,000 Italian super cars competing in the world's largest Italian car show. It was the maiden concours outing for our 350 GT, just days after completion of an intensive 9 month mechanical and cosmetic overhaul. Although we are obviously very proud of the work we have done to this beautiful Lamborghini, we were just happy to get her to the show on time and had no aspirations about winning any awards. Accordingly, we were absolutely thrilled when the car not only won its class, but also won 'Best of Show' for the best Lamborghini at the event.

Huge congratulations to the owner of the car, and also thanks to my team who really put in the hours just to get this amazing car to California.
Thanks also to our friends Valentino Balboni, Jeff Stephan and Andrew Romanowski, all of whom made significant contributions to this exciting project.

Update report - August 1, 2019
Putting the finishing touches to the new spare wheel well just a couple of days before the car is to be collected and taken across to Monterey, California for the Concorso Italiano event on August 17th.

Jake is putting in some serious hours fabricating the
new wheel well before the car heads to CA

With the new well installed and painted, the
underside of the car is greatly improved
We also made a new wheel cover out of Beech wood

New jack and tool roll are perfect replicas
of the originals

this beautiful car ready for Concorso Italiano

We are continuing to work our way through a list of items to be corrected before the car is sent to the Concorso Italiano event in Monterey next month. The inoperative wiper motor has been removed and will be repaired. The first two images below show just how much of the dash has to be removed in order to access the wiper motor! In the meantime, Jake has begun fabricating a new spare wheel well. We are very fortunate to have a second 350GT under restoration in the Team CJ Works so we have an original wheel well to use as a template. We have also been busy refinishing the steering column and upper column housing and upgrading the coolant hoses to the correct 'wrapped' style hoses with OEM style Serratub quick release clamps.

Installing the rebuilt Weber carbs

We have been looking for a set of original specification, Italian made, 40DCOE 20/21 Webers since we were first entrusted with the care of this 350 GT. With a HUGE vote of thanks to Andrew Romanowski of Lamborghini Club America, we now have not only a complete set of these rare and elusive Webers, we believe we may have the actual carbs that were installed on our car when it was new!

As if that wasn't enough, we are thrilled that Andrew had renowned Lamborghini technician and authority Jeff Stephan rebuild and restore the carbs before shipping them to us to be reunited with the 350 GT. Jeff did a spectacular job and we look forward to installing and tuning them in the next few days.

We have also been busy dealing with a few cosmetic issues, specifically some chrome and brightwork which requires straightening and re-polishing.

Fully rebuilt 40DCOE 20/21 carbs

Front side lamp housings had some cosmetic issues
and will be re-chromed
Rear bumpers also removed for minor dent repairs

Having completed a major mechanical overhaul over the last seven months, it is now time for the 350GT to spend some time at its new home! Later this spring we will be preparing the car for an appearance at the upcoming Concorso Italiano in Monterey, California.

I am pleased to report that we now have the first stage of the mechanical overhaul underway. As we work our way through the repairs we will also take the opportunity to correct a few points of originality along the way as the owner wants this car to be as original and concours correct as possible. For example, the DCOE 40 Webers currently installed are Spanish made. As production of Webers moved from Italy to Spain in the early 1990's, clearly these carbs cannot be correct for this car. Our research leads us to believe that the 350GT had Webers specific and unique to the 350, namely DCOE 40 (20) and DCOE 40 (21).

I am delighted to report that we will have this exciting project underway very shortly.
