Well, it’s off to a new owner, I really liked this car because it was the only 330 2+2 that I have driven that felt like a GTC, super quick and smooth with an endless progressive throttle travel.

Overhauled Porsche 911 Engine

A very good customer showed up last fall with one of my favorite cars, an early Porsche 911 Coupe. While the car did run and propel itself down the road, it needed lots of mechanical attention to remedy oil leaks, weak compression on a few cylinders and a huge list of other things. We decided that in order to enjoy the car in the future, we needed to go through the engine, transmission, brakes, clutch and other less dramatic things such as the heat and vent controls and … windshield wiper blades!

Here is a video of the engine running on the test stand to check for leaks and the adjustment of the ignition system and carburetors. This engine has German made Solex/Zenith carburetors, an Italian produced Magnetti Marelli distributor in combination with a French S.E.V Marchal Alternator.

Laycock DeNormanville Overdrive Unit

We used to send these Overdrive Units off to a specialist to be rebuilt but something always went wrong on the first test drive. Come to think of it, sometimes they were leaking so badly that we had to take them apart and re-seal them before knuckle busting installation into the chassis.  Considering all the time to properly package the part, the cost to ship the 40lb crate as well as the weeks it takes to get it back, Nate decided to overhaul this Austin Healey 3000 Laycock deNormanville unit on his own. All the parts are available so once they arrive, he’ll slam it back together and test it by spinning it up on the lathe so he can be confident things are right before the installation.

I just don’t get it

This is a subject that I write about frequently because I just don’t understand why Ferrari Transmissions are bigger than the engine in front of it. We just had a transmission out of a 1955 Ford Pickup that was the size of a shoe box and a 5 speed ZF transmission out of a Maserati is tiny compared to the 5 speed out of this 330 GT 2+2. If I seem frustrated it’s because getting this Parthenon out of the car is a job that only Zeus can handle.

This transmission works well but the synchronizers are worn to to point of having a chrome plated polished look instead of the required rough cast finish but all the bearings and gears are perfect. We used to replace the operating sleeves on these transmissions but they take so long to “wear in” that I feel they are doing more damage than good especially considering how well they shift with the original parts re-installed.

Transmission Numbers on Ferraris

I don’t offer much helpful information on this blog but want to share some photos of the font and progression of transmission, engine, and axle number stampings on Ferrari castings. From now on, i’m going to photograph stamps on Ferrari castings as I have the ability, the transmission stamps are hard to photograph because the interior has to come out for access. These are all photographs of Transmissions from 250’s and 330’s.  As things progress, I will post photos of Engines, axles and trans-axles.

Boxer engine Almost finished

We are almost finished with the 512BB engine overhaul. Casey has done the bulk of the assembly work and has done a nice job making all of the details correct and look fresh without going totally nutty. We are waiting for the vibrational dampener to return from the repair shop but we can make the engine run on the test stand without it, keep tuned for a video of it running on youtube.

While waiting for the engine machine work and pistons to be custom made, we overhauled the transmission and addressed a few other issues to make sure the car will be solid for driving this summer. This engine is slightly enhanced and we will have dyno sheets of before and after the overhaul.

Ferrari 512BB engine overhaul

The 512 BB engine is back from the machine shop, as you may remember from an earlier post, this engine came apart with great difficulty. The machine shop had to open the cylinders up .020″, cleaned the deck surface, polished the crank and had new custom forged Carello Pistons made.  Since we had to warm and cool the block while using all kinds of special pullers and tools, I was most concerned with making sure the sealing surface of the case halves were totally flat and ensure the line bore for the crankshaft was within spec. Surprisingly, these surfaces were straight as a die and the line bore was perfect however, we do have a few little nicks to weld up and file down.  Now is the time to clean and detail the castings.

Overhauling a 330 transmission

We’ve seen synchronizers worn to the point of being polished to a mirror finish and still work properly but the ones in this 330 transmission still had the new looking cast finish but it wouldn’t go into gear without grinding on downshifts. It turns out that these synchronizers were likely to have been cruddy replacement parts that don’t have the proper spring tension or the correct measurements so we are going to replace them as well as the operating sleeves.

Some of the operating sleeves had chips in the teeth but the transmission looked good inside but we still replaced the bearings since I feel that they are likely to get damaged when removing them from the shafts and case.  This transmission is a monster!

How to get a 512BB engine apart

There were a bunch of leads as to why this engine overheated but we aren’t sure exactly which problem led to its demise. The water pump looked nasty, maybe it failed and blew all the water out of the weep hole or maybe the head gasket failed. Once we finally got the case split, we found that the cylinder protrusion on the 7-12 bank was .007-.012″ where it should be about .003″ from the deck surface so the gasket may not have sealed around the water passages.

Since the engine was burning a little bit of oil when it ran and the 2nd gear synchro needed to be replaced, it reinforced the need to overhaul this drive train. We are thinking of enhancing the engine with slightly higher compression pistons and increasing the flow by matching the intake manifolds and testing and enhancing the intake and exhaust ports.

A problem with the Ferrari Boxer design arises when you wash the car or drive it in the rain and water pools around the main bearing studs causing a major corrosion issue between the case and the studs, “gluing” the halves together. We made steel blocks that use the main bearing nuts to push the halves apart as you un-thread them but it didn’t work at all. We ended up making hardwood wedges to drive in with a hammer and 3 portable hydraulic cylinders so after nearly a week of labor the job was finally done.

Have a look at the massive amount of corrosion on the studs!
