Does anyone know of a list of original engine numbers for these cars? If not, can we distingish from the number whether the blocks were originally fitted in Ferraris, Fiats or Stratos's. Thanks
Mike Morris in his book "FIAT Dino - Ferrari by Another Name" states that there was no differences in the 206, motors were randomly grabbed off the assembly line and sent to Ferrari for the 206. For the 246, FIAT supplied the parts off the assembly line and sent them to Ferrari for assembly but again there were no special builds for one car over another. Just that Ferrari assembled the 246's. The Stratos was different as they purchased the motors from FIAT.
Stratos blocks are different in that they don't have the usual engine numbers embossed on the vertical part of the block. They have a Lancia logo and engine number embossed just above the other blocks but on the horizontal side of the block.
I have not seen this book, but this piece of information is WRONG. The crankshaft for the Ferrari 206 is different. It would not be possible to grab engines "at random" to put into the Ferrari.
uh what ? not sure where you got that idea, would love to know what you think might be different because they are EXACTLY the same. Many a FIAT Dino has been sacrificed so that its motor could live in on in a Ferrari. I would suggest you learn what a FIAT Dino is, its not a normal everyday FIAT, may I suggest you start with http://www.dinospider.com/
206 and 246 crankshafts are different. All 246 engine blocks are the same except for the difference I pointed above. The other engine parts are not all identical. Pistons and camshafts change between Ferrari, FIAT and Lancia. The most different is the Lancia adding to the differencies above different carburators, different inlet manifold as well as other minor stuff.
The crankshafts are different. The Fiat Dino is an externally balanced shaft while the Ferrari has an internally balanced shaft. The Fiat Dino has an offset weight in both the harmonic damper and in the flywheel, and the shaft, damper, flywheel assembly has to be balanced as a unit. The Ferrari has no eccentric weight in the harmonic damper. The Ferrari has an aluminum/rubber bonded damper that bolts to the flywheel end of the crankshaft. The actual flywheel, ring gear, clutch surface is driven by this damper assembly. To keep the flywheel and clutch assembly true, it runs on its own set of bearings on the clutch pilot shaft. There is no eccentric weight anywhere on the damper, flywheel, clutch unit. A 206 Fiat crankshaft CAN be used in a Ferrari 206, but it would be necessary to use the Fiat Dino harmonic damper with the eccentic weight and it would be necessary to create an offset weight in the flywheel/damper assembly. If a Fiat Dino crankshaft were put directly into a Ferrari 206, there would be a very bad engine vibration. The Ferrari 206 parts listing shows "Albero motore con equilibratura Ferrari".
I defer to the all knowing F-Chat gods who refuse to ever believe that Enzo would ever allow his motor to go into a lowly FIAT, you must be right and history must be recorded incorrectly.
Mikeyr The Fiat Dino is a very cool car with great sounds and they rev to the moon. While they share most engine parts with the Ferrari Dino I do know that they built in less horsepower into the Fiat, primarily from different camshafts. I did not know about the different crankshafts as reported.
My dino engine builder has clocked up several ferrari and fiat 246 cams and has found they are all the same.
What is the difference between 246 engines whose numbers start 135C 000 and those that start 135CS 000?
Yes, they are the same cams but people here on F-chat like to think they are not, same with the 206 cams. Some myths never die... And I for one will stop trying ... I am out of this thread.
