(Update: looking like I may have sourced what I'm after.)
OK, I've stripped my Giardiniera's engine, and the camshaft is looking like it really has done every one of the 165 000 miles that the car has done.
It looks like none are available new, but the wear on mine I fear makes it beyond a stock regrind (0.5mm variation across exhaust cams!). Does anyone know of any new in stock somewhere, or can recommend an outfit that can regrind... so I'm after a donor camshaft too!
I'm aware that camshaft profiles have moved on a bit in the past 70 years, so am open to a better performing profile than original.

Camshafts for the Giardiniera are just about impossible to find these days. I have a Canadian colleague and we are trying to find a 35/75/75/35 camshaft for the engine that he is re-building (and has enlarged to 652cc)---they have dissappeared off the face of the earth! I am advised that "Piper Cams" can, and will, do a regrind to 35/75/75/35 specifications for you----they are a well established and respected Company in this field. Also try "Newman Cams"--they are also a well respected Company with a good reputation, and are in Farnborough (KENT). However, fitting a "re-ground" cam can sometimes involve extra work with regard to push-rod length and rocker-tower height. It is worth hunting around with regard to price---they seem to range from approximately £250 upto close to £500! It would be worthwhile speaking to the Camshaft Companies before hunting for a 'donor' cam---they might be able to succesfully re-grind your knackered item.
 
I did speculate recently with Tom as to whether the camshaft from a Fiat 126 Bis would fit a Giardiniera as it would certainly have an improved profile. Tom said he had looked at this and the answer was no, forgotten the details but could it be engineered to fit ?
I had experience of camshaft upgrade reprofiling with Newman Cams. As a 126 car club project at a time when hot cams were unaffordable I got together with a pal and we collected as many 500 and 126 cams as we could, rejected a couple but had 17 that we thought were viable. I negotiated with Newman Cams and sent them the whole lot. After inspection they rejected a further three. I then asked them to proceed with a batch of ten. The process involved the regrind to a sport spec then finishing by nitride hardening. At the time we were able to sell them on to club members for about £100, £140 pounds less than those advertised at the time.

The BIS camshaft will FIT INTO the 120 (Giardiniera_ engine but WONT WORK unless some engineering is carried out. (1) When the BIS cam is fitted into the '120' engine, an electric fuel-pump will be required as the cam-lobe to operate the fuel-pump operating rod on the BIS cam does not align with the postion of the the pump's drive rod in the '120' engine. (2) The centre bore for the oil-pressure valve must be added tothe BIS camshaft. Now, not having been able to put a BIS cam alongside a '120'cam, so that I can see the reason for this, I am not quite sure what that entails.However, if those 2 problems can be overcome, the BIS cam should give better performance than the stock '120' cam.
