Ferrari 365 Boxer on the chassis Dynomometer

As I mentioned earlier, I brought 3 Ferraris to do some test runs on the Chassis Dynomometer in Burlington. I was very impressed with the results. Ferrari has been known to embellish the horsepower figures of there engines but we found the actual readings closer (not as high) to the factory figures.

Here is a youtube clip of the 365 BB run

Overhauling a 330 GTC transmission



After doing all kinds of work on a 1967 Ferrari 330 GTC we are now going through the transmission. We overhauled the engine last fall and after our customer spent the spring and early summer driving the car he realized that the synchronizers were too worn for him to enjoy driving the car.

We are going to replace the bearings at the front of the transmission but all of the other bearings look great. All 5 synchronizer bands have been replaced even though the second and third gear synchros were the worst.

These transmissions are straightforward to work on provided you do not have to deal with the spacing on the pinion shaft.

Another Blue Ferrari 365 GTC/4


I bought another Ferrari 365 GTC/4 recently, a car that is blue chirao metallic just like the color we painted our project C/4.

With original paint and interior this car is so special. It is clean and detailed nicely even with some old age related deterioration. The interior has that special smell associated with leather, wool carpets, latex foam mixed with the years of oil and gas fumes!

The other reason that this car is so appealing is because the engine and transmission have been overhauled. There are photos of the engine break down and of it on the dynomometer, service invoices and dyno sheets. The engine does not leak a drop of oil and the transmission shifts like a dream.

As of this entry, the car has sold but I still have my 365 GTC/4 for sale. We are currently assembling the body, getting all of those tiny trim pieces assembled around the door frames. This car will probably be one of the nicest ones out there with fresh engine, trans, brakes, paint, and detailing. I am excited to do another post on this project.

Ferrari 330 GTC transmission



What would cause the shift lever to move forward and backward upon decelerating and accelerating? I am not talking about a 1/4″, more like 1-2 inches. The transmission was quiet and the ring and pinion are totally silent so it could not be the pinion shaft cluster that was loose.

We pulled the trans-axle and something very unusual happened, we found a simple problem that required a very simple solution! The forward most ring nut on the main shaft was loose and it did not do any damage to the rest of the gears or bearings. With this nut loose, the selector rings were moving which made the shift lever do the voodo dance.

Ferrari 365 C4 project


We have been working on the C/4 project and have the engine apart and ready for shipping to the machine shop. The engine ran well but was very smoky, big surprise. With only 45,000 miles on the odometer I was curious to figure out what caused this oil burning, was it broken piston rings, bad valve stem seals or guides? We do not get to open up too many original engines around here so it is a pleasure to work on something that we know has not been messed up by someone who does not know what they are doing.

Upon close examination I found all of the piston clearances to be prefect and no rings broken or even having lost there spring temper. What we did find is a weakness that most Ferraris suffer from — absolutely worn out valve guides. In looking at the design of Ferrari cylinder heads, there appears to be no reason for complete wear-out at 40,000 miles. They have long guides and they do not suffer from seats and guides that come loose like other engines. My experience tells me that with these engines powered by multiple carburetors, the valve stems often have the oil stripped away from excess gasoline, creating this intense wear. I will also go so far as to blame the driver of the car for constantly “jabbing” the throttle, which shoots raw gasoline from the accelerator pump circuit into the cylinders washing down the bores and valves.
Needless to say, this engine is going to have new pistons, rings, bearings and a full valve job. It will be fully detailed and running as new. I am looking forward to posting the before and after photos.
