1965 Lamborghini 350GT

Major mechanical overhaul and minor cosmetic restoration work.



Update report - April 23, 2019
Cleaning up the air cleaner covers.

Air cleaner covers have been painted bright white
at some time in the past
Original cream color beneath the stickers

Covers have been media blasted

Repainted cream, per original
Original stickers saved and re-used

The modified Ansa exhaust has now been ceramic coated satin black and is ready to install.

When parts are not available, we are very fortunate to have talented machinists
who can make them for us on the team. Corey fabricated a complicated, multifaceted, brass fuel line fitting for the 350GT, as well as a new bronze bushing for the steering box cap.

Headers and exhaust have now been ceramic
coated in satin black

Inside tips have been powder coated in
International Orange, per original
Ansa stickers add the finishing touch

Brass stock for fuel line fitting

Original bushing in steering box cap was damaged
because of a previous lubrication issue
Boring out the recess in order to press fit a new
bearing bronze bushing

Machining the new bronze bushing
New bushing now installed

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.

Header flanges show evidence of exhaust leaks
After cleaning, the flanges are being surfaced
to promote a better seal

Left hand flange has been surfaced flat
We used a CAVIS stamp to replicate the look of
the original plug wires

Modern performance and reliability with the
look of the original plug wires
Plug wires and rebuilt distributors now installed

Starting to lay out the fuel lines and fabricate
the fuel line banjo fittings

Banjo fittings will be cadmium plated
Rebuilt and restored Konis with new springs

Good progress with the suspension, brakes and exhaust.

The suspension control arms have now been powder
coated semi-gloss black

not adequately lubricated
Much needed rebuild of steering box underway

Replacement rear suspension uprights
Corey polished the steering shaft and machined new
bronze bushings in the machine shop

We discovered that one of the rear control arms
was bent!
This angle demonstrates the issue more clearly

With the control arms straightened, we will now have
them blasted and powder coated semi-gloss black
Brake calipers were in a terrible state

Rebuild in progress using new seals and
stainless pistons

Valve covers have been refinished

Worn clutch pack will be replaced

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).

Impressive front grille on display with the
car raised in the air

Suspension control arms will be refinished in black
Aftermarket ride height adjustable shocks will be
replaced with shocks and springs of correct spec

Spare wheel well is incorrect and will be replaced
Distributors will be rebuilt and refinished to
concours standards

Seized fuel sending unit was the cause of the
inoperative fuel gauge

looks like it was designed by a Swiss watchmaker

Webers are incorrect and will be replaced with
Italian made originals

Fan thermostatic switch is defective
Several bushings have perished and will be replaced

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