What I was saying was that the FERRARI Dino V6 was not only made in many sizes but also in 60 degree as well as in 65 degree bank angle plus with a three pin crankpin crankshaft (con-rod journals) as well as with a six pin crankpin crankshaft.
if there was ever a version with 3 crankpins we might think of the Franco Rocchi developed version for the Tasman series
the unsuccessful 1967-9 F2 (Rocchi version of course production-derived) Dino 166 engine had 18 (then 24) valves
the (Rocchi) Tasman Dino was a lengthened F2 chassis with 2404cc and had 18 valves/285 hp then 24 valves/305 hp
it won the Tasman series once for Chris Amon and once for Graeme Lawrence
Bandini's 1966 F1 V6 car had 18 valves and was the precursor
all photos seem to show the same rather large block stagger indicative of the 6 pin design
unless we are to imagine these engines had the large block stagger but only 3 crankpins
where's the evidence for a 3 crankpin engine - ever ?
Ferrarichat website says the 1958 296s wasn't a Dino but a 60 deg 'half a Colombo V12' - but I guessed 'half a Lampredi V12'
