So the cam out of a Punto 75 would go straight into a 1242 SPI engine then???
Sorry don't mean to sound stupid, I'm just double checking.

apparently, yes it is worth doing. The 55 is the same engine as the Cinq Sporting and it's recommended by a few people 
It's alleged that the 75 cam is the same as the one Novitec (IIRC) sell as a fast road cam for the 1108/1242 spi cars.

Well, I can only try...
My logic is this: The 1108 and 1242cc SPi both use the same head and cam, its the 75 (1242cc MPi) that has a hotter cam because the multipoint fuelling needs it..so logically, It should swap in directly for the 1108 / 1242 SPi cam, hence fun!
hey,
i write from Denmark and drive cinq. sporting se it here : http://www.bilgalleri.dk/html/gal_visbil.asp?ID=7960
i write to tell you all that the punto 1,2 8v 75 hp, 1,2 60 hp and 1,1 55 hp all uses the same camshaft! = no ekstra horsepower!

The 1242 mpi cam HAS!!! got aprox 1.2mm more lift over a standard 1108.A 1108 cam has 0.8mm more lift than a 999 fire engine uno.Ive just done a cam swap from my cinque 1108 into an uno 999 no problemo and ive got a mpi cam for my cinque ready to fit.reckman said:
There are certainly two part numbers an the Fiat Parts Systemreckman said:
7723029 which is compatible with M1 ,M2 ,M5 ,M6 and is shared with the Cinq and 7772866 which is compatible with M3 (the 1.2MPI) and M7 (1.2SPI CF2 176B4000)
So it looks as though some later model 1.2SPIs used this cam also.
I hope this helps

Someone (Blitzen?) quoted the cam timings and lift figures a while ago, the Cinq/Sei SPI, Punto 55 and 60 all use the same cam but the 75 is a slightly longer duration. I'll take Quatermass's word over the lift.
