Engine Suffix ID Location
I found a 71 Corvette that I'm really interested in, but I'm having trouble finding all the info that I want from the VIN and Engine Code. The VIN is 194371S106269.
But the problem is that the plate on the front of the engine is illegible. The PO claims that the engine was rebuilt and since most of the numbers are missing from that plate, I'm guessing that he's probably telling the truth. However, there were enough numbers for me to make out that its the 3970010 block. But I'm missing the Engine Suffix ID. Is there anything that can be done to confirm that this is infact the original engine or is the information just gone?

I think you might be out of luck. If the VIN number is gone from the block stamp pad there is no way of knowing if it's original or not. The number 3970010 is the block casting number and was used from 69 to 79 in both 2 and 4 bolt mains. What is the plate you are referring to? The numbers are stamped on a boss at the right front corner of the block and a plate.

Here is the picture of the area that I'm talking about. As you can see there is some crap on the area that has the numbers on it, so some of the numbers are missing. But is there another area on the engine that may have the Engine Suffix ID that I'm looking for? Or what exactly is the number that I'm looking for to see if its the original motor or not?

That is where I was looking. That is where I found the 3970010. Or actually i found the 01007, i can't see anything else on that area. Actually the numbers that are visible are barely because they are sanded off.
I put the VIN in at a website and it gave me a Jan. 12, 1971 date. And then on the Plate inside the Driver's door is the code F12 does that play any part with the birth date of the car?

ok....I brought my "Corvette By The Numbers" book with me on vacation at the beach.......and my wife says I'd never use it!!!!! The code for "F' in 1971 is January, which would match the vin,,,,so your plate is right, so now look on the block for a date code cast into it. for example, my 68 has a cast date of "D 16 8", which is april 16th, 68.look for something like that, should end in either "1" or more likely, "0" , since its a january car, let me know, john (in Avalon NJ, with the kids)

75 shown, others smiliar. There should be two stamped numbers on the engine pad. If the numbers are not there, the block has been decked.
