Turbo Block Casting Numbers

[icanfixall]

As I understand it the turbo blocks have a casting number of 10809000C3 and the non turbo blocks are 10809000C1. Can anyone confirm this with their turbo block and non turbo blocks? Thanks.... I know the 7.3 block serial numbers started at 500,079 and up to 1,116,330. Then the turbo blocks started at 1,116,331.....

Here's a picture of the casting # on my block. Casting # is 1809000C3. I don't know what happened to the first "0" in the number, but it is a IDI Turbo block.

Here is a link to an article from Engine-builder.com that gives a lot of info on casting numbers, its got a lot of good information:
