hey i have a ford 351 cleveland that i inherited i have had a look over it and found some numbers i just wanted to know what they represented the numbers are:

D2AE-CA
4C11
1975.3

and if i need any more numbers please tell me what numbers and where to find them, any help at all would be appreciated. Cheers and what an engine like this is going for?

 

your in luck, this is a 351c cobra jet. 11 march 1974 casting date code. Remove the pan from one head and look for # like d1ze-da.

 

is this a rare or expensive version of this engine and how do you tell if this is a genuine gt model? also if opossible what is trhe going price for this

 

Pretty much, yes.
This is an engine forum on a truck site so I can't guarantee how much help you'll get,
but it seems you're referring to some sort of car (Mustang, Torino, something like that?).
Never heard of a GT engine. Regardless. I'd start with checking the VIN; there's a VIN
decoder on this site, last item in the drop-down menu under Articles/Specs.
No idea but I'm sure it's dependent on completeness & condition.

I suspect others (trinogt comes to mind) will offer more information .

 

ctubutis is right. And also came in cougar and cyclone in 71-72. I also check in the other book and for d2ae-ca it could be a 71 351c 4v or 72-74 351c boss,71 cj, ho '72-74 4v.if i'm good with the casting date code # it's not a 351c 4v from 71 but it could be 351c boss or 72-74 4v. if it's a 4 bolt main bearing-cap it's equipped with split-lip rear main-bearing seal. Special block cast with thicker cylinder walls and siamesed bores for for use carries an XE192540 casting number. Give me the # under the valve cover.... 8 smalls bolts...
