Polo Storico will do that, I think. They are doing a great job. But you can ask the framebuilder, he is still on duty. The 400GT frame is more heavy than the 350GT. Same advance as the Miura.
Ok that's all you have I have interviewed Marchesi he has confirmed me that exception of the body supports the structure frame is identical You have also to read the brochure specs and homologation specs... for instance width is identical at 1,73 m... lenght 4,46 m... for 350 GT, 400 GT, 400 GT 2+2 I have interviewed Marazzi in Varese who also confirmed to have used the 400 GT 2+2 frame with a new body he has created...
not my job too... but if you want to argue, you need to feed us too... I have identified the 23x Interim... Among them, Gary Bobileff has restored 5x of them, frame is same, as I wrote there are slight différences in the structure to support body, as well as small differences in some other areas... but globally frame is identical, it is the 1st design conserve for the developpment of the range and in terms of sizes too ! to illustrate here is a 400 GT frame...

Those tubes have nothing to do with any Lamborghini built GT at all! L-E Image Unavailable, Please Login
the front square sections yes, it was a 400 GT 2+2 modified to receive a Bizzarini body... but you can look in De La Rive box book they are pictures of the frame too.
It's kind of early over here yet for popcorn but I'll go warm up a batch with some butter, salt and if this goes long enough we can even break out the bourbon too! I have to admit that I'm sort of fascinated about all of this murky early 350/400GT stuff and have never quite followed all of it. The very idea that Lamborghini had any hard standards on this stuff back then and kept meticulous records about it is hysterical enough all by itself! I can well beleive that Olivier has worked very hard trying to figure it all out. Too bad that the thread's starter is no longer with us because Fred was veritable fountain of information on this stuff. But we've got some other good folks here. Someone should drag Gary into this thread. Probably kicking and screaming ... Carry on ...
Will Marchesi share the drawings? That would settle this discussion! I know that between the 350GT and 400GT, the mounting for the rear differential is not the same. (ZF versus Lamborghini rear-end) And yes, I know the switch over point is another topic.
The mounting support for the transmission is different on cars with ZF-gearbox or Lamborghini-gearbox. And the trailing arms for the rear uprights are mounted forwards on two-seaters (big rear window) and backwards on the four-seaters (small rear window) and Isleros. But the chassis never had any round tubes! L-E
Isn't Olivier saying that the round tubes modification were for a custom Bizzarrini body that was placed on that specific chassis? That's how I read it. And here's the link, Bogus Bizzarrini, Bogus Bizzarrini: 1967 Lamborghini 400GT
Or you can just check my 350 GT Register: 350 GT / 400 GT Internazionale | Ferrari - Lamborghini Register Nederland The cars that left factory as 400 GT are listed, and otherwise the cars are listed as 350 GT 4 litri, as in fitted with a 4 liter engine afterwards. I will not use the term Interim on either of them ;-) Ciao! Marcel
