60's and 70's Maserati Factory Replacement Engines

The engines were stamped with their “base” number regardless of which model car they were mounted. Wet sump motors were 107, Dry sump 115.

 

The next 4 numbers should then match the vin number of the chassis, that will tell you if it’s the correct engine

 

Do you have the classiche documents from the factory?
On my old khamsin, the engine was changed on warranty the first year of it’s life. On the official documents the old engine number was changed by hand to the new one. But you could still see the old number below. Would that be considered ”matching numbers”?

 

How about posting the number? Someone here might be able to tell you where it possibly originated?

 

Your engine number is actually AM107/A *1544*, so apparently a replacement engine for chassis 1544 (not 1600 as you stated before).

Here is the corresponding picture for the engine of my Indy 4.9.
The engine is a 107/49 base, meaning the wet sump V8 with 4900 cc, *2054* being the number of the Indy car:

The chassis number is, as expected for matching numbers, AM116/49 *2054*, AM116/49 corresponding to Indy's with the 4900 engine:

The 107 simply states the base model of the engine in this case series 1 Quattroporte. In addition to the S1 QP, it was also used in the Mexico, Indy and Bora all of which have 107 stamped engines. It’s been a while and I could be wrong but the A may indicate that it is a 4.7. The 1544 is the chassis, I would guess probably from an Indy.

Ivan you want to correct or confirm me here?

 

No there is only one number on the engine that is AM107/49 *2054*.
As said by Italiancars, the engine model is AM107, it's the wet sump model that started on the QP (which is an AM107 Maserati model), here a 107/49 because it's a 4.9 engine.
The chassis series is AM116 because it's an Indy.
*2054* is the actual number of the car (associated with the two previous model identifications, either of the engine or of the car).
So each classic Maserati has in principle two identification numbers, one for the engine and one for the chassis but both contain the same last *number* in the series, here *2054*
Some, like the QP that started with the V8, may have only one identification number such as AM107 *....*
Hope I was clear enough

 

I see I was not clear enough...
Let's try differently.

What I stated was the possibility of two prefixes, even for "matching numbers" cars.
For my car (an Indy), this is through two different prefixes (AM107 and AM116, for the engine and the chassis respectively).
This is because Indy's use the same base engine (wet sump) that was first installed on the QP (AM107).
But the specific last number of the car (*2054* in my case) will appear on both complete numbers, of the engine and of the chassis, and they will "match".

In my last but one sentence, I said: Some, like the QP that started with the V8, may have only one identification number such as AM107 *....*
It's also the case of the Ghibli (AM115) that started with the dry sump engine.
Ghibli's have a unique prefix that is AM115 that will also be the prefix for the other dry sump V8 engines of that period.
Any matching numbers Khamsin will also have its engine number starting with AM115 while its chassis number will start by AM120. This is because Khamsin's have the dry sump engine that started on Ghibli's.

Incidentally that was discussed in more detail by Enrico in the link below:
http://www.maserati-alfieri.co.uk/alfieri06xxxxxx.htm

Now obviously your Ghibli has an unconventional engine because of the "1".
However if the engine number of your car would be AM115/1 *1544* (so with the same ending number *1544* than on your chassis), I would say that it had a factory replacement still qualifying for matching numbers.

BUT, if I understand correctly your last statements:
For example, I have AM115/49*1726* only, on both my chassis and engine.
And also:
I've just checked again the engine number....So, number is : AM107/1 *1544*
I would say that your car doesn't have matching numbers as the last identification numbers are not the same on the chassis (*1726*) and on the engine (*1544*).

Even more, it is not certain that your replacement engine would be a dry sump 4.9 engine because its prefix is characteristic of wet sump engines (AM107) and does not contain the number 49 after the /.
But that would be very surprising as the assembly of a wet sump engine on a Ghibli would not be straightforward, not to say impossible...
Hope that helps

 

Is this engine in a Ghibli? If so would that car happen to be black or a dark color?

 

Ghiblis never had a wet sump, only dry.

 

I sent the picture to Fabio and he replied.

Joe,
This engine seems to be an Indy engine as you are supposing.
Around the Indy engine numbers stamps there is a little confusion. I have already experienced some Indy 4,7 with the engine number code AM107/1.

Should be nice if you can find on the engine the engine internal number (usually on the Indy engine block are present two engine internal numbers. One is stamped on a little plate riveted on the engine block, and the second is stamped on the block on top of the thermostat housing (or on the back of the engine block, left side near at the clutch bellhouse)).

Try to find it and I'll better check.

Ciao and have a nice day
Fabio
