Matching numbers...

When did Ferrari stop stamping the chassis number on the engine? If an engine doesn't match the chassis on a non-concours car (ie, driver), should the value be affected?

Just curious...

I believe the 275GTB/GTS had matching numbers but the Daytona did not. So right around that period. Would think 330GTC's have matching numbers but just a guess.

Personally, I would not disqualify a car if the numbers did not match but would pick at the price a little.

 

??? As far as I know every road going Ferrari chassis (and almost every racecar) has a specific engine number which corresponds to the VIN.

My understanding is as follows: On early cars it's simpler e.g. my car VIN is 7919GT and the engine is 7919. The later cars have a longer VIN but within it is the engine number.

Am I missing something?

Regarding the value: non-matching engines have been discussed thoroughly in another thread within the vintage section. The conclusion was that the value is slightly negatively affected however; this should be an issue on identical cars. Condition is much more important especially with drivers.

Ferraris have had a separate engine number from very early on. It seems to have been stamped on engine block as soon as the casting was checked and accepted for the machine shop. This is why engine number is stamped on rough surface. For your car this number should be #1324.

When engine was mated to the chassis, they also duplicated the chassis number, now stamped on milled surface on right side of the block.

Duplication of chassis number seems to have ended at the time of Fiat take over and while earliest Daytonas have both numbers, the later cars only have the engine number.

What about the 166 MM Barchetta: didn't it have an out of sync system (a lower engine number compared to the chassis number)?

 

Thanks for the clarification Kare. I learned something new.

Thanks all for the information. I figured it was something like that. A 1971 Daytona I am looking at does not have the engine number stamped on it, but the early Sheehan car (supposedly one of the first Scaglietti prototypes) does have it.

 

That's good information. So 330GTC's had matching numbers as well.

 

By the 308GTB production, for example, the engine was no longer stamped to match the VIN, but had a ID number based upon ????.

It doesn't match the VIN.........
