Engine ID help

Hi guys. Here is my engine that came with my 59 frame. The block code is C8AE 6015 AC I'm looking at pix to see what it may be but I'm not seeing a lot with the intake on the driver's side. Looks like a 223, but with a 68 block code ? Could it be a bit of mix and match ? Any thoughts appreciated.

223. There is no mix and match between those and the later 240/300.

Maybe its C3AE.....

Or--long shot--a replacement block cast in '68. But that's beyond the 24 and 36 month warranties of that era. Industrial?

Best bet is it's C3, just so crusty it looks like C8.

Look for the date code cast into the block. See:

That's the stuff. Got out my mini wire brush and cleaned it up and it is C3. Which makes the date stamp of 4B18 way more sense lol

@Kruse, Fram is new to my so I'm just digging into it. Its an 87ish AOD trans with a custom adapter. So my guess is its stock to that trans. Here is a better pic.

The AOD is a delicate flower and usually needs a throttle valve properly adjusted to shift right and not burn up.

So when you get to that point, check that out.

Swerving suggestion.....
