From my research, the 1961 246 SP engine (Tipo 171S) had two plugs per cylinder. This is per Doug Nye's Dino: The Little Ferrari pg 110 and Godfrey's Ferrari Dino SPs, pg 36 (EDIT: also Prunet's Ferrari Sports Racing and Prototypes Competition Cars pg 274). There are even quite clear photos in Godfrey's book of the twin plug arrangement on pg 78 (from chassis 0790) and pg 40 (of the 246 F1 engine from which the 246 SP engine was derived). I'm happy to furnish scans of these photos for verification, however I'm not sure how to do this without running afoul of wikipedia image use guidelines. These sources contradicts the official Ferrari 246 SP page currently linked as a reference for the 246 SP having single plug ignition. This seems to be an oversight on the Ferrari website's part, as the other references are very convincing with photo evidence. I believe it would be an easy mistake to make, as all other Dino SPs did use single plug ignition in their simpler, SOHC V6/V8 engines. However, as it does contradict a "factory" source, I though it best to post the reasoning here on the talk page before I make a change. Prova MO (talk) 00:48, 12 December 2019 (UTC)[reply]

Yes there are oversights so go ahead with new reference for dual plugs. Or add that two arrangements were possible or used. Maybe at different times or on different cars.

Dino 196 S had both vee angles of Dino V6, but on two examples and Ferrari wrote only one of them on their website.YBSOne (talk) 10:26, 12 December 2019 (UTC)[reply
