Dear all
few weeks ago I had the favour to purchase a standard bore 351 Cleveland as a standby engine for my 72 Mach 1.
Casting number reads D2AE-CA 2D14.
Heads are identified with a "4" and a "dot".
I've learned that "2D14" decodes casting date 14th April 1972.
Now the questions:
I'm not really sure about the second digit, whether it's a "2" or "Z".
Can I exclude the "Z"?
It has a 4-bolt main, but is it a Cobra Jet too?
Anybody out there who can help?
Best regards
Frank
Well you can definetly rule out the Z, It is a 2. D2 designates 72. The D is for the 70's and 2 is the specific year. Wish I could help more. But this is all I'm sure of at the moment. Some body else will fill in the rest of the blanks. JTS 71 Mach1
My hope was that Jack could answer that question for you.
I am not sure. D - stands for the decade (1970's)
2 - stands for the year (1972)
A - stands for Ford cars
E - stands for Engine group
The -CA is where I am not sure. The C - ?, the A - an original design.
The rest of it you have figured out.
Here's hoping someone else comes along with the missing information.
In 72 and 73 cobra jets and 72 R codes were the only ones to get 4 bolt mains and 4 V heads
A 72 CJ would have open chamber heads

4 Heads, a pair of each style, open and closed chambers came with the block. The open chamber heads with screw-in studs and guideplates.

I'm just wondering about some details:
I've read in literature, that all 351 cleveland blocks with cast "D2AE-CA" should come with 4 bolt mains.
One of my blocks doesn't.
Cast "D2AE-CA" and "1K4" is found but also 2 bolt mains!
Is this regular and the literature quotes wrong?
Best regards

Open heads with screw in studs IF ORIGINAL would have been 72 r code HO heads - but usually someone modified them
Ford mixed and match motor parts [ blocks ] to keep the line moving
People have found 2 bolt mains in Q code mustangs
Have also found 4 bolt mains in H code torinos and even station wagons.

There really isn't anything all that impressive about a 351CJ. A 4 bolt block is useless for street engines. I don't know about in your area but around here I can find 2 bolt blocks for free. I'd consider selling off the 4 bolt and put the money towards the blocks machine work you are going to have to pay for. You are going to have to bore, deck and align hone the mains on any used block anyways. The open chamber 4V heads aren't a very desirable head unless you plan on putting a blower on top. What are you wanting to build ? What trans ? What comp ratio ?

a friend of mine asked me for the 4 bolt main. I prefer torque and enjoy my streetable 351-2V. And yes; we are going really fast on the streets.
Lucky you getting 2 bolt Cleveland for free. There's no possibility for that in Germany. We have to pay for them.

I had a 70 Mach 1 that I recently sold and prior to me selling it I took a photo of the casting number on the block behind the starter and contacted Ford to see what it was. They gave me the Ford web site that list all casting numbers on their blocks, heads, etc....Mine was a D2AE-CA 26E and it was a 4 bolts main and their chart showed it was the same block used in 72 for the CJ, Boss and HO motors..What made the difference was the heads and internals....and being a 4bolt.....I hope this helped you....Kelly
Jack Roush has been on record as stating that the two bolt main Cleveland blocks are just as strong as the 4 bolt mains engine. Its only at extreme racing performance at continued high RPM that there may be the possibility of cap shift if any.
The D2AE-CA casting can be either 4 bolt or two bolt mains for 1972.
There is I believe only a difference in chamber volume on the 72 vs 73 CJ/ HO heads if I remember correctly. Ill go get my books and let you know on this one.
Personally I could care less these days about the casting marks as long as I personally know its a real Cleveland.
I gave a set of cobra Jet (open Chamber heads) to my best friend the other day. We are building the engine with performance in mind. To compensate we milled down the studs and will use a set of screw in studs and a roller rocker set up.
To raise compression we will use pop up pistons and have the top of the pistons milled down just a tad to keep a fair compression ratio without getting out of the pump gas range.
The rest is all preference.
Whe a person considers those restomodded cars that now sell for more than concourse cars....Ill have my resto mod car that looks original and with more original factory options but without the R code and concourse price.
