The article doesn't say whether the "twin-cam" only means "2 camshafts" or "DOHC". ARE THEY OVER-HEAD or not?!? --129.247.247.239 (talk) 15:03, 8 May 2012 (UTC)
 * Just look where the twincam redirects so you see answer what is twin cam -- >Typ932 T&middot;C 16:15, 8 May 2012 (UTC)
 * "Twin cam" doesn't imply whether the cams are in the head or block. Twin cams in a block are rare today, but they have been used in the past.
 * For the Alfa, it's obviously twin overhead cams. This is stated several times in the article already. Andy Dingley (talk) 16:18, 8 May 2012 (UTC)

Whither the 1900?
According to this article:

The Alfa Romeo Twin Cam engine was introduced in the 1290 cc Giulietta of 1954.

Oddly, I had thought that the postwar Alfa Romeo Twin Cam engine, chain drive and all, began with the Alfa Romeo 1900. Apart from the displacement, what difference was there between the 1900 engine and the Giulietta engine? Sincerely, SamBlob (talk) 22:11, 14 March 2015 (UTC)

Verifying origin of some 8V Twin Spark engines
As one of the edits made to this page I removed a reference to a 1995 cc 8-valve engine, even though it appeared in some of the other wikipedia language pages (it and fr) and even in some of the external references I had found. In the edit comments I noted that I was unable to find a clear reference to this engine except for the Alfa Romeo 155 Q4, which was described as having a Lancia (Fiat) engine. Since then I have found that the carfolio site lists another Alfa 155 with a 1995 cc engines and describes it as an 8-valve, SOHC engine of Fiat origin., which is somewhat reassuring regarding its deletion from the Twin Cam article. Both the larger Twin Cam engines and the 2.0 L Fiat Twin Cams have 84 cc bores and the Fiat is shown as having a 1995 cc version with the same stroke listed for the 1995 cc engine used in the 155. I have found many conflicting reports regarding both the manufacturer and features of the 1995 cc engine and am looking for a definitive reference (preferably printed) that clears the matter up.

The other version I am looking for confirmation for is the 1.7 L, 1749 cc engine.
