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.
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.
