Really canīt remember the data of the cams except the price was about 650$ for a pair. A short story really, visiting the Alfa museum and then Autodelta in order of buying a pair of cams. When arriving at Autodelta I asked for Mr. Carlo Chiti (!) but they told me he was out of office that day, so an engineer would help me. While fetching him I tried to get a glimpse at the racecars in the shop, but there was a veeery long wall stopping insight to the racecars. Then came the engineer and told me the price of a set of camshafts, which turned out to be too expensive. So we went on with our vacation without the Autodelta cams. After returning I bought a used set of Autodelta cams from Sweden for half the price. The specs of these were 11mm 310 degr. 60-70/70-60. The Alfetta GTV2000 did about 190 kph with the standard cams and 210 on Autobahn with the Autodelta cams.
Later i got some german articles from visits to Autodelta what was behind the long wall which I unfortunately could not pass...a lot of tipo 33 and Bertone racecars.

Then probably you will appreciate some photos from Settimo Milanese. These are from an article at the time I was in the area.

Autodelta Cams 11.0 mm
Gabor:
I researched most of my old Alfa cam data and could not find any "Autodelta" cam`s specs close to what you recall. The "opening & closing" nunbers really just don`t work, and I manipulated all I could in the cam data I use to build cam profiles & separations.
Autodelta supplied Alfa cam stocks ( usualy the unground 032000 early core) to more than one outside supplier to grind their cam`s for them. There are a few sets of the true "Autodelta" unmarked cams from their early development stage around. I just traded a set of of 10.6 & 11.3 cams (unmarked except for 032000, and some Ausca scribing) to Gordon Raymond (who worked with AUSCA for his AUSCA GTA Spider, ) that were "Autodelta" sent to AUSCA in the `60`s that were used in their GTA`s & in a customer car that I now own. His research seem`s to indicate the 11.3 cam was originally ground as a GTAM intake by C&B.
I have a set (pair) of original 10.mm (10.4 lift) unmarked 032000 cams if any one is interested in them.
I have profiled all of the cams that have gone through my hands so as to be able to reproduce,or repair them.
Sorry I could not identify your`s.. 
Richard

But FWIW, Fusi's engine data re: bore & stroke on the GTA-SA are incorrect. The SA engine has the regular 1600 GTA bore & stroke 78mm x 82mm. I used to believe Fusi's data until I saw several GTA-SA engines at Angelo Chiapperini's shop. He gave me this information and I measured the bore myself. The bore and stroke given by Fusi was from the 1600F2 motor that was also fitted to the GTA in some cases.

Very interesting observation, Alleggerita. I also saw that the SA and the F2 engine had the same bore and stroke acc. to Fusi, but did not check. As we all know the Fusi book has a lot of small faults which have to be found, but otherwise itīs an impressive work!
So with the help of the Chiti Grand Prix book the two engines are mentioned and I list the data here:
1967 1600SA b x s 78 x 82 mm, 1590cc 240Hp/7000 twin cam, twin plug, 2 valve, supercharger.
1968 1600F2 b x s 86 x 68,5 mm 1591 180Hp/8000 TC single plug, 4 valve, carburettors. The data suggest that there was even a 2 valve version of this engine. Maybe an early model.

Yes, the 1600F2 was definitely available in a 2-valve version using the regular GTA head and carburators, but possibly also with the narrow angle 2 valve head.

That's a version of the F1 turbo engine designed by Gianni Tonti for the 1987 season. Noting to do with GTA/GTAm/F2 16v/etc.
Fitted in a Ligier during winter testings, program cancelled under pretext because Fiat didn't want Alfa to compete against Ferrari in F1. Poor reliability, never went beyond preliminay tests.
I have full specs somewhere, but not at hand. I seem to remember that the topic has already been raised on the BB. 1500cc, and an estimated output of 800+ HP in race tuning.

Well I know a little bit about it, but cannot remember having seen bore/stroke and power data. Short story I have heard that Alfa agreed to supply Ligier with egines in 1987, but only after a few races and some testing Rene Arnoux openly declared that the engine was no good(it breaks like glass), and so the Alfa management who already were doubtful of participating in F1 had the reason to pull the plug. So Ligier raced the rest of the season with Megatron/BMW engines. So this Alfa 415T engine is that last of the Alfa F1 engines. I think I have also seen a photo of this engine with only one turbo. So here a photo of the car and a link. If somebody has the engine specifics please come forward!
