Unidentified Engine ID

I have a 1980 Chevy C-10. I'm in the process of changing the oil pan with a one-piece fel-pro gasket, yet when i placed it on the oil pan it didnt make a good fit. So, i proceded to lookup the engine ID to see if i actually have a 350 from a 1980 chevy. Perhaps its pre-1975 or something. The ID read V03198O0. Unfortunately, after looking at several decoding resources on-line, I can't find anything that decodes this ID. Can anyone offer me any help with this problem? Thanks.

Well one thing thats off with your code is it has 5 numbers. Suffix codes have only 4 numbers. If we cant get the given info from the suffix code then look on the back of the block and get the casting numbers. Then also on the back will be the date code which will look like this example:
C 6 2 The C is the month A=Jan B= Feb C=Mar so its march
6 is the date, the 6th of march
2 is the year, 1972
We confirm the year by looking at what years the casting number was avalible.

You need to work the last 3 symbols, theyare usually letters with the three symbol codes. The V tells you its built in Flint, the 03 is March, the 19 is the 19th day of that month. The "8O0" needs to be all letters in capitals, Although there are some codes starting with 3 and 9 but they all use a number and one capital letter. Cracking this code will give you the year, displacement, and installtion.

Get the block casting number from the drivers side top of the bell-housing bolt flange. That will translate into a group of years those castings were made, the bore which will separate 302/327/350 with 4 inch bores from 305s 307's, 283's, 265's with smaller bores, or 400s with larger bores. So while not exact this gives you a tighter range of possibilities.
