1965 Lamborghini 350 GT

Major mechanical overhaul and minor cosmetic restoration work.



 

 

Update report - June 22, 2019

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.

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.

We have now received the rebuilt and restored Konis, fabricated and installed new "Cavis' plug wires with Bakelite plug wire ends, and begun the process of fabricating the new engine bay fuel lines. We should have the exhaust back from being ceramic coated early next week, along with the new fuel line banjos which are currently being Cad plated.

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.
