Hello Ricardo,
I did a bit of Fulvia reading and checking, There doesn't appear to be any difference between normale and 2c camshafts nor the 'V' angle, if you check specifications in 'La Lancia' they are the same, the increase in power is mainly due to twin solex Carburettors & inlet manifold, and with the increase of compression ratio to 9-1 instead of I think it was 7.2 -1 with the Normale.
I'm not sure if this was achieved with a change of pistons or the 2c cylinder head, so if you don't achieve what you want from the Nardi kit, then it would seem a relatively easy upgrade if the pistons are not involved, if they are, skimming the cylinder head may help.
Dellorto 32 DHLB's are better built than the solexes, they have the advantage of all the jets etc being accessible from the top rather than having to take the solexes off to get at them as they are underneath.
There is no visible difference in overall performance but the dellorto's run and idle smoother than the solexes, and seem to stay in tune for a long time. in fact I think it's something like 6 years since mine were touched, if not longer.
I also fitted a 'filter King' filter & pressure regulator about 2000, as the early Fulvias didn't have a fuel filter and I was pulling all sorts of rubbish up from the petrol tank, I have also fitted an electric fuel pump up near the fuel tank with a lighted switch on the dash, this is only used for priming the carburettors; after the pump stops ticking I pump the accelerator pedal 6 times, pull the choke fully out, then operate the ignition switch, she always fire 1st or 2nd pull, I don't touch the pedal until the running has settled, then push the choke nearly home, and pick up the revs on the pedal, touching the pedal before then may result in flooding the plugs and or stalling.
I also have a simple electronic ignition system fitted which only use the points as a trigger so there's no wear on the contacts.

Hello Brian,
I dont have the "La Lancia" book, and on the books that I have there is no indication of the camshaft. Do they say if the 1C and 2c camshafts are the same? Same opening angles etc?
If they are I'll keep mine, and skim the cylinder head to reach the 2C compression ratio. I know the 2C valves have a greater diameter.
I also have the same starting ritual! But I dont have an electric pump yet, so every time I have the car stopped for more than one week I have to take out the fuel hose going to the carb, suck the fuel back up the hose and connect it again. Not very practical!
Can you give me the specifications of the pump you have?

Hi Ricardo,
Just found the specification for timing for Normale & 2c, as well I checked the Tavoli Parts list, and I'm afraid first look in La Lancia that I thought indicated the camshafts are the same, was incorrect.
I've attached 3 documents that are self explanatory, I've also highlighted the differences in pink for the timing.
Information from the Tavoli regarding part numbers and use.
818.00 Normale Cylinder Head Part Number 1107160
818.100 2c Cylinder Head Part Number 1107674, this was also used for GT and 1.2 Coupe.
818.00 Inlet Valve Part Number 1107188
818.100 2c Inlet Valve Part Number 1191412
818.00 Exhaust Valve Part Number 1107191
818.100 Exhaust Valve Part Number 1191413.
So in fact there seems to be nothing in common whether or not you could fit a 2c Cylinder Head Complete I'm not sure. but you'd also need to fit the Solex twin Choke carbs and manifold to go with the head.
The Final Drive on 818.100 2c is higher than that for the 818.00 Normale.
hope this helps
