GTAm

[borrani]

The only reference I've seen to the name GTA'm' standing for 'maggiorata' was in one of Pat Braden's books. Everything else seems to indicate it as the GT America, which really has the strongest argument, even Don Black referred to it as the GT America, as did The Quadrifoglio magazine.

As has been made clear above, the GTAm is in no way a GTA.
http://www.mid-atlantic-aroc.org/Racing/GTAm.htm is just an outstanding resource, also stated above!

I think the only reason they sell for less than GTA's is there aren't as many venues to race them, as Europe's FIA historic racing likes '65 and earlier cars.

Cheers!

To Torch ,
three expanations are given fot the GTAm acronym:
1.Grand Turismo America
2.Grand Turismo Allegerita magiorata
3.Grand Turismo Allesagio magiorato
the correct one according to Maurizio Tabucchi inside his book "GTA" is the 1st one because the car is based in the 105.51 US edition 1750 for homologation , the GTAm was never an Allegerita because it used all steel chassis and panels unlike the GTA which used Peraluman 25 lightweight panels on a steel chassis, on some GTAs even the floors were produced from Peraluman 25 , as for the SA yes it stands for sovralimentata but the whole acronym is GTA-SA only 10 such cars ever produced the car being the same as a GTA 1600 , the difference was that the engine in its induction used two superchargers which were driven from a high pressure oil pump spinning to 100000 rpm , this magnificent engine produced 240 bhp , I have a friend who has driven a GTA-SA he could not hold the car in a straight line under accelaration in any gear.
Last January there was an original GTAm chassis number 1531042 sold from a dealer in US for 92000 US dollars !!!!!
Original GTAms are hard to find the reason is as Pete mentions they were not a specific chassis number as were GTAs and GTA Juniors.

Ok, Takis.

I had no idea that the Am wasnt Allegerita with Peraluman 25. Too baad

Then you're right!

Sorry everybody...

I guess only Alfa Romeo know, but if you do an internet search of GTAm that is what ALL the sites you will find say, ie. America. Pete

I also ran across this quote:

"Period factory publications made it clear that the name was a reference to the car’s American connections: in the Jaunary, 1970 issue of Il Quadrifoglio (v.5, no. 14, pp. 68-69) the full name listed in the text is "1750 GT America." Nevertheless, there has been considerable confusion concerning the meaning of the name GTAm, with some authoritative sources suggesting that it stood for GTA "maggiorata" (enlarged) or that "Am" was an abbreviation for "alessagio maggiorato" (enlarged bore). "

Thus a better bore stroke ratio than the long stroke 1962cc engine AND bigger!!. They also were built up around a mono-sleeve, thus they would be a great little motor ... much stronger.

That, and the 1750 shares the stroke of the 2000 at 88.5mm.
