    Are you asking about the grey GTB 09233?
    Marcel shared these details when it first appeared> 'Grigio Notte Metallizzato 106-E-28 Salchi'.
    No comments regarding the blue paint of the other GTB so far...

    no, I was wondering about the car pictured in this GHG post:
    https://www.ferrarichat.com/forum/posts/148702734/
    and then in this Harry-SZ post:
    https://www.ferrarichat.com/forum/posts/148768140/
    Maybe I got it wrong but I don't think the car in these photos is 09233.
    Thank you.
    Greetings

    Good afternoon everyone,

    We happen to have an early 275 2 cam and a 275 4 cam both finishing their engine rebuilds at nearly the same time and thought you all would enjoy seeing some pictures of them together to showcase their similarities and differences.

    First up is the 275 2 cam, immediately noticeable is the 4 point engine mounts like on 250 cars (and others), the three carburetor setup and obviously the 2 camshafts vs 4. Also of interest are the oil filter pedestal, oil fillers/breathers, the oil pan and the angle drives/distributors. The UFI oil filters painted and decal-ed to look like the vintage Frams are also noteworthy as the modern Frams have had their stand pipes removed.

    Up next we have the 4 cam engine. Immediately noticeable are the 6 carburetors, 4 camshafts, 2 engine mounts, the tilted angle drives, the oil filter pedestal and the oil breather tubes. You can also see that all the oil breathers are routed to the intake manifolds and the vapors are pulled by vacuum into the intake tract. The dry sump oil lines are also visible and are quite a departure from the 2 cam as is the routing of the water lines.

    Its great that we can still get pipe work done the way it was done originally. On the mufflers, I had a NOS pair of primary mufflers that needed the collector pipes finished. I also had a pair of NOS headers for the 4 cam and a complete original NOS exhaust system. I will post pictures of the rest of the exhaust later.

    Never having owned (or even contemplated owning) a 275, I've never had occasion to delve into the exhaust system; that 4-inlet muffler is "wild"...

    Judges might take off a point for the welds being too nice... :)

    Mind you, I have to admit that when I had my new exhaust made I told the fabricator that he had to use stick welds...

    Looks great Greg.
    I assume you verified the correct fit/shape etc of the NOS headers on the engine in the car before aligning/fabricating pipes and their flanges for the mufflers ?
    It’s just that I’ve had couple of occasions with Daytonas when installing NOS headers brought up some surprising misalignments.

    Hi Timo,

    Actually, i was being completely serious.

    I’m not sure what method TimeValve really used, but I asked that they replicate the look of the welds on my original exhaust (which was rusted-out, but otherwise looked like a factory set-up). TIG and MIG don’t generally look as messy, so I was basically telling them to make everything look like it was a sloppy stick/electrode weld...

    I can’t say enough about how pleased I was with TimeValve; exhaust was essentially perfect...

    Interesting.

    My experience with Daytonas, however limited it may be, has revealed only two welding techniques having originally been used in their construction, MIG (a.k.a. Wire feed) & Oxy-Acetylene (a.k.a. Gas), former mainly used for chassis and coach work support structures (which I usually refer as "space frame" for the body/sheet metal), while latter is/was mainly used in sheet metal/panel, exhaust, fuel/oil tanks and other (liquid related) plumbing type, thin wall component construction.

    I can't recall ever seeing Arc (a.k.a. Stick) welding having been used in most, if any and including Ferrari, automobile manufacturing, hence my assumption.
    Construction, Heavy Equipment, Trucks, Ships, etc, yes, but not in passenger cars.

    AFAIK, TIG (a.k.a. Heli-Arc) welding didn't become common or used used in automotive manufacturing or repairs until over a decade after Daytona production had ended, but is now commonly employed even in vintage car restorations, regardless of how inauthentic it is, both in appearance and technically.

    The most interesting observation is/was the MIG weld qualities between the frame (by Vaccari ?) and space frame structures (by Scaglietti). Former usually having been able to produce very nice results, while those by latter can make one wonder “WTF ?”.

    P.S. My apologies to all for veering slightly off topic from "Official Ferrari 275 GTB pictures".

    Well, I was talking about an exhaust, so it was really a comment more about Ansa's weld quality. I should have been clearer about that.

    I probably also should not have said anything about the exact weld technique used. I really just meant that the welds have the appearance of being sort of rough. I've seen stick-welds that could be mistaken for TIG welds, so I really have no idea what Ansa actually used.

    Back with some more pictures showing the evolution of 275 components, in this case transaxles. In the photos we have 275 short nose, 275 GTB/4 and 365 GTB/4 transaxles. You can see that the short nose employs a completely different mounting method than the later designs. Additionally the short nose used an open driveshaft without a torque tube whereas later designs enclosed the shaft in a torque tube. Both of these design changes resulted in large improvements over the earlier design. You can also see that the case for the 365 GTB/4 is significantly enlarged compared to the two previous iterations.

    And here's a video of the short nose engine running on the stand, as requested. Just a temporary setup to perform some baseline adjustments before reinstalling the engine, including a rough carburetor synchronization.

    Here are some photos of the 4 cam setup for some test running and preliminary adjustment on the engine stand and a few more before we started placing the engine back in the chassis. The engine is now back in the car awaiting final run in.

    Special thanks to Sunoco for generously providing the dry sump reservoir.
