I recently bought a XE with a 351 cleveland. I was doing some research on the numbers above the water pump to the right on the block. I got some information about it and I was set. Then a couple weeks later I was getting ready to pull the engine and took the starter motor off. Then I saw a number which said D2AE-CA, I did some more research, the internet said that it was a cobra jet engine, I wasn't convinced because it said it only came in 3 or 4 differen't types of vehicles and a falcon wasn't one of them. So I want to know what type of engine it is. Thanks guys!

See if this is of anyb help

I read that article before and I saw the same number (D2AE-CA) under the pillow block section, I really understand can anyone help?

More importantly...the engine number itself...on the passenger side of the integral cam chain housing.....is it the same as the chassis number...if so, it is a matching numbers car.
If it has a prefix like 'AL', then it is from an 'F' series.

What is the 'F series'?

Yep, That's because D2AE-CA is the engineering number for the block casting and doesn't designate the particular type of engine. It just means an engineering revised casting produced from 1972-on.
F-series is the truck series like F100.
