Engine identification

[l.duckworth14 10]

I recently got a 69 stang from my brother and we think its gotten a engine replacement somewhere in its life. Im not as familiar with engines as i would like to be and im trying to figure out what it is anybody know where an ID tag or P/N might be?

The "correct" engine size for the vehicle can be determined from the VIN. Identifying which engine is currently in the vehicle can be more of a challenge. A 260/289/302/351w pretty much all APPEAR nearly the same.

[l.duckworth14 10]

Iv read that theres supposed to be a tag or something near the distributor but havent found anything yet. could be hidden by some grease and gunk yet but got any insight as to where i should focus?

http://www.vintage-mustang.com/topics/decode/decode.html All the way to the bottom you can check the vin tag to see what Should be in there. If you measure across the front intake bolts on a 351w it should be about 9 1/4" and a 260-302 will be about 7 1/2".

 

Post a pic maybe its a big block? or 351c?

If the engine has been replaced, it's likely that the aluminum engine tag is long gone. Read the casting number off the intake and compare what you have to online pictures of a 289/302, 351 Windsor and a Cleveland.

Count the number of valve cover bolts. 5 bolts FE engine 390/427/428... 6 bolts 289/302/351 Windsor... 7 bolts 429/460... 8 bolts 351 Cleveland or possibly a 351 modified or 400....

I recently checked my intake manifold for a 302 and it has the part number:

 

C8AE-9425-B

 

 

You can see it on top of the intake running up under the front of the carburetor.

 

There should also be a date code that you can see if it matches up with the build date for your car. Mine was 9A17 which should be 1969 Jan 17 which is good because my car was built in January.

Here's like every Ford intake known to man.

Well according to the vin it should be a 351 2v and there are 8 bolts on the valve cover and the number on top of the intake is F013726548 also had a holley 4160 carb on it. Anybody shed some light?

[wtfwsat 10]

well the 8 bolt valve cover narrows it down to a 351c/m or a 400. According to the F0 number on the intake that would be a 1990 but doesnt make sense because from what i can find the 351c was last made in '74 and the 351m/400 was last made in '82. Pics would help...

 

Just looked over the part number again and noticed the 13726548 is the firing order for 351's and the 400 but still not sure about the F0. There should be a casting number someone like the above picture C8AE-....

F.O. = Firing Order

 

He needs to look someplace else for the casting/part number

[cobra460jet 10]

If I remember right the block casting numbers are behind the starter. Good luck with that one. You can look for codes on the water pump, distributor, and the intake. See if the valve cover has a sticker on it for info. There should be a date code close to the oil filter also. If the t-stat housing bolts to the intake its a small block windsor engine. If it bolts to the block its the cleavland family. Check the intake for more casting numbers.

[l.duckworth14 10]

yea i feel stupid now i suppose "FO" means firing order. So its down to a 351 c/m 0r a 400 when i get home ill look for some more numbers see what i can find out.

[l.duckworth14 10]

Ok on the back of the intake it says "WEIND 7517" distributor says "motorcraft D2ZF 12127 GC 2F14" the motorcraft and 12127 were raised writing the rest was recessed stamp. Sorry no pics cant load them

[Fordrevhead 29]

Aftermarket intake but thats a 1972 dual point 351C distributor. Its likely that you have a 72 351CJ engine which isnt a bad swap at all.

[l.duckworth14 10]

Very nice got any ideas how to confirm it or is that a pretty solid indication?

[Max Power 74]

I never look at valve cover bolts in the Cleveland vs Windsor ID attempts. Cleveland style motors have the stat housing in the TC cover, windsors are in the intake. Lots easier that counting bolts.

Block ID# is above the starter motor, theres a flat spot on the block.

Look along the same side between the freezeplugs for a casting date code.

[l.duckworth14 10]

Good news I pulled out the starter and found the block id number D2AE-CA 2A22 which according to some quick research is a 351 cleveland. Thanks for the help guys youll hear from me again!

[Fordrevhead 29]

That vin indicates it is a 72 Cleveland but without a head casting number or checking the main bearing caps for 2 or 4 bolt you dont know which one. Concidering that the intake is aftermarket, and the rarity of the HO (aka later CJ) I suspect you have the 2v head 2 bolt main version.

 

351C-2V Generic low compression 351C, '70-74

 

351C-4V HO Very Rare, Low Compression, Solid Lifters, "High Output" 1972 only

 

If your head casting number starts D0, D1, D2 you have 4v heads but those could have been swapped two.

 

With that block casting number the only way to tell for sure if it is a 4 bolt main is to drop the pan. Ford would just grab a block and machine it to accept the beefy caps. If you knew the car it came out of and the vin is another way.

 

Another thing to note is that EPA began in 72 so if you had an early build you can have the 71 closed chamer quench heads (2.19" IV/ 1.71" EV)otherwise you get the open chamber heads with much lower resulting compression and often smaller valves (2.04" IV / 1.65" EV). There are so many examples in this year period that you really have to measure the valves to be sure.
