I don't think it makes any difference at all. The fact that the car is an SV, versus being an S or P400 is the plus in terms of value.
A manufacture date is stamped into the end of the block directly above the clutch. Each cylinder head will have a similar date stamp on the same end. Image Unavailable, Please Login Image Unavailable, Please Login
I'm going to guess that it is the sequential block number. The block I pictured is 404 and it's from around the middle of production. It could of course mean something entirely different. It's not a number I've ever need for anything, until now The engine number is the 5 digit number stamped into the valley between cylinder banks (not visible in this picture).
No these were not recorded, only the engine number. You will find out that the date of manufacture of your block and the cylinder heads will precede the delivery date of your car by quite some time...
looking at other web sites (mz) i'm thinking stands for the block ( i d) where for the numbers than would run some what close to the car biuld number??? yes
hey tim what was the car biuld number for the block in the pic? i think the block mz number may match the car production number!!
386, Close, but no cigar. I think it's just a block number so their foundry/machine shop could keep track of how much work they were turning out. Once an engine was assembled the 5 digit engine number was the important one.
No, the block numbers generally do not coincide with production numbers. As Tim says, they are just a number put there to keep track of them. You've seen pictures of rows of engines on the floor ready to be put in cars as the came down the 'line. Generally, they just reached for the closest unit. What are the dates on your cylinder heads and block?
That depends on if they were talking to the Italian tax commission, or the customer. Which one would you like to be today?
