???, looks like a GTAm head to me. Definitely twin plug and the 1300 engine has the same bore spacings as the 1750 does it not? ... thus a natural progression for the 1300 development.

I also have never heard of Cosworth building a head for Alfa Romeo ... seems a bit strange when Alfa Romeo have Autodelta ...

I find it much more stange that it looks so much like a Fiat head, specifically the cam boxes. Is it possible Autodelta or whoever grafted Fiat pieces onto thier head?

Being an Alfista, it's the other way round; Fiat possibly grafted Alfa pieces!
From the Alfa Performance Options Catalog #104 (2M) dated 11/71.

Hi Max,

It was not 16v head. This one was 8v, 165hp.

Yeah you are right...that is what happens with the value....the car was not competitive in Europe anymore, and there was a change in racing classes at home (they were switching from 1300 to 1150 and 1600ccm). Of course, car was litteraly worth nothing.

But those were nice times I think. My dad was a student and without any support from parents he could afford to acquire such a car for races. He was appreciated in racing circles since he always had best engines, so he tuned the engines to lot of other guys on a grid to earn some money.

Nowadays, I could not imagine that a student affords even to sit as a passanger in 156 GTA ETCC Autodelta racing car for a single lap!!!!!!!

I hope you and your dad would be able to find the original car.
Would be a nice end.

Best regards from Spain, Alvaro.

The engine picture is a GTAm engine, no two ways about it.
The catalog page shown a few posts back, clearly shows the mistaken "60*"
head business, a mistake appearing in many other occasions! It looks like the guy writing the descriptions in the catalog back then, didn't know much about AR competition stuff.What about the proofreader-say what??!!
Excellent historic pictures, ahh...we should have been born about 10-15 years earlier (me, at least!)

*&%$#@, goofed again, bigtime! My humble apologies to the esteemed audience!(deep bow!) The engine is the GTA 1300 "Testa stretta" which means, a narrow angle (45*) GTAm type cylinder head. There were two types of GTAm heads, this one had a much smaller combustion chamber, due to the smaller bore. In this head,smaller valves were used than in the 2000GTAm, as there is no room in the chamber for the large valves.Here again, the old competition parts catalog is wrong, listing the same valve sizes for both heads. The 45* head is not very well known as there were not many made. With it,these 1300 engines could make over 175hp, as compared with the best 1300 GTA engines which managed 165hp tops, also with Spica. (This is all 8-valve stuff).
Sorry about the goof-up Karlo!
