Help with some engine codes?

67Chevy_hotrod, This motor is a 1965. Aren't you looking for a 1967? If you go with the 1965, it's going to need a complete rebuild right? If so, that's going to get a little pricey. Why not hold out for the 1967, or for the money you could just drop a crate in there, and come out a grand or so ahead. If you really want a 1967, keep looking, they're out there.
If you continue your search for a 1967 block, try to get all the block info before you post it up. I will keep this thread marked so I'll see your questions as soon as you ask. Here is a breakdown of the numbers on a 1967 block.
There are 3 numbers that you will want to get. Sometimes you can get a definitive answer from just one number. Sometimes it takes two numbers to get a definitive answer and sometimes it takes all three. The partial vin is the fourth set of numbers, but partial VINs aren't found on truck motors till the mid seventies. So a 1967 truck motor won't have a partial vin on it. The three numbers you should be most interested in are:
1. The casting number, You already know about this one.
2. The engine ID number, F0916EB This number consist of 3 separate codes. The first letter is the engine assembly plant code. Your 1967, 327 will be either a F or V.
The next 4 numbers are the date of assembly code. It does not include the year, just the month and day of assembly. (I was often used as a 1) 09=September, 16=16th day of Sept.
The last two letters are the application code. EB in this example. This code is the most useful, It will tell you the engine size, horsepower, trans type, carb type, vehicle type and smog equipment, if applicable. Application codes were reused over several years, so the block date code is often needed to decode it correctly. In 1967 application codes were two digits. The engine assembly plant code+the assembly date code+the application code make up the Engine ID number. This number is stamped not cast.
3.The block date code. The block date code is cast into the block(opposite side from the casting number) and should precede the assembly code by at least 1 day. I have found 2 to 4 days to be the norm, but as long as the block date code precedes the assembly date code, your good to go. The block date code will be in this format C047(on a 1967 block). The C is the month(March) the 04 is the day(4th) and the 7 is the year(1967). Some later blocks used two digits for the year, but you can usually determine a single digit year from the range on the casting number.
With this info you should be able to decode any block you come across. You can use the links in post #2 to decode the numbers you find. The pic in post #3 will show you the locations of the numbers. You can always post your numbers here for a double check.
Mechanicalman is better than me, to ask about the small journal. He is a master mechanic and can give you much better advice on the subject of rebuilding, and small journal vs. large journal than I can.
Hope this helps if you decide to continue your search.
