    Thank you Joe! Do you know something more about the history of those two cars?

    I fully agree. The chassis is very well designed and exteriorly stiff. It is in fact an example of the art of engineering of stiff light weight structures. Some missing or bad welds have in most cases no influence on the integrity.
    Interesting are also the small differences between the years 83-85-87.

    The bearing seats of the 1983 5000S oil pan and the 1987 QV oil pan are absolutely identical and all bearings are precisely aligned.

    The new oil pan that I bought some months ago brand new from the factory is scrap!

    Two bearing seats are 0.12mm out of alignment with the other two.

    Yes, the 1987 had extra speakers in front of the sill. Realize this is the RH sill pictured!

    The removable paint is actually Developer Spray used by welders to spot cracks in repair work. Some companies remarket it as "Scanning spray" but the composition is the exact same (I see you're using the Helling one). The spray has a propellant (either alcohol or acetone) and basically talcum powder mixed in. The propellant pushes it out and evaporates quickly leaving the talcum powder behind. The Helling one has alcohol.

    Be careful with plastic parts - the alcohol can etch the plastic and rubber and do irreversible damage. Very hit and miss. Painted parts, it's fine. But bare plastic, I've seen issues (I laser scan vehicles as well).

    Indeed, as with every aspect of Countach production from LP400 to 25th, there were incremental changes that occurred as production went along, and they occurred randomly and did not necessarily coincide with the commencement of new variants.

    DaniT That is awesome! Can I please please please have the laser scan data :( I've 3D modeled a Countach LP500s inside out but only based on photos, I would die for a laser scan! Jet-x was actually trying to get his hands on a Countach to scan but timings have not been in his favor.

    Please? :)

    Here is a render - along with 3D prints of a 1/4 scale. I did stop printing seeing that I might get my hands on a an accurate laser scan data. I'd rather print an accurate however close my hand 3d model may seem.

    I could cry of excitement.... That's how much that would mean to me! Countach is my favorite "thing" on earth... it saddens me that if I was at this age 15 years ago I would have been able to afford one... and now I will never be able to and so the next best thing is a virtual one.

    Jimmy, you are doing a very nice job and the 3d prints are looking very cool.

    To receive the best results we have contracted a specialised engineering company for scanning the car. They are using high end equipment that would be for us not economical to buy as we do not need to scan every day. Also the processing of the 3D data into solids was outsourced due to the special software required for a productive quality job. This all is quite expensive and time consuming. Please understand that I do not want to give those files out of my hands.

    I found recently some 3D data of a Countach on the web. Was this your data? If not I will try to find it again and send you the link.

    I wish you good luck with your ambitious project. Please post pictures of the model you are building.

    I am modifying the FI engine internals to the DD specification. For this we will install the DD pistons and DD camshaft. The rest of the internals are the same.

    On the first picture you can see the FI piston p/n 001420828 with 9.3 : 1
    On the second picture you can see the DD piston p/n 001420801 with 9.5 : 1

    The small difference on the dome is quite well visible. It looks like that some material has been removed from the DD piston to get the lower dome of the FI piston.

    Improvised reverse engineering to get the exact geometry of the DD cam shafts. For measuring the cam shafts we are using an taken out of service 4 axis Haas CNC mill.
    The cam shaft is step by step rotated while the probe in the spindle is measuring the lobes. Later the data is plotted to get the exact geometry.

    The p/n for the DD cam shafts are the following:

    1220848
    1220847
    1220845
    1220846

    According to my information they are no more available.

    No, we did with the originals, but since they are not stainless steel they broke after about 10 years.

    The Magnetti Marelli S158E distributor disassembled. Unfortunately there was not performed any preventive maintenance on this distributor. Many components are worn or damaged.

    Does anybody know a good source for Magnetti Marelli spare parts?
