8h19 is the casting date, and doesn't help identify the block. The block was cast August 19 1978 for what it's worth though. Look around for some more numbers/letters

It looks like you may have an 1985 Block; which may not be a roller block depending on the casting date.

What are you aspirations for this motor? Do you plane to make mods to the engine?


Use this to figure out your block:

DECIPHERING FORD PART NUMBERS
Submitted by macx / 02-28-05

Here's how to decipher Ford part numbers. As an example we'll use D1ZZ-6675-C.

The first two digits indicate year. The letter is the decade.

A = '40s
B = '50s
C = '60s
D = '70s
E = '80s
F = '90s
G = '00s

The third digit designates body line:

A = Ford full size
D = Falcon
E = Escort
F = Pinto, Maverick, Falcon
G = Early Comets, Montego, Cyclone
H = Medium/Heavy Duty Truck
K = Edsel
L = Lincoln Mark VII
M = Mercury
O = Fairlane
R = Capri
S = Thunderbird
T = Pick-up Truck or Bronco
U = Econoline Van
V = Lincoln
W = Cougar
Z = Mustang
{there are actually many more}

The fourth position signifies the Engineering group

A = Chassis
B = Body
E = Engine

If it is a Service Replacement part the designator will be:

Z = Ford Division
Y = Lincoln-Mercury
X = Original Muscle Parts program
M = Ford Motorsport, SVO, FFRP

The center number, four or more numbers or letters, is the part number. The A at the end of the number indicates that the part is the first version. If it was revised once, it would be B. If it was revised again, it would be C, and so on. When they run out of letters, it becomes AA, AB, and so on.
So if we decode this number, D1ZZ-6675-C, we come up with the following:

D1 = 1971 model year
Z = Mustang
Z = Ford Division Service Replacement part
6675 = the group number for oil pans
C = The third version of this part
 
The E5AE-6069 part number is an 1985+ 5.0 EFI timing cover. Doesn't mean it wasn't booted to an earlier block. I also believe it can be mounted to either a 351 or 302.


The blocks eating numbers should be located at the sides of the block underneath cylinder 4 and 8. I forget which side, but it would be located along the area where the freeze plugs would be at the rear. If the date code is correct and it's a 1978 block, the part number should start C8AE- or something like that. There may be a RF- prefix in front

So everything u said still doesn't tell me the size of the motor I wanna rebuild it but dont no for sure what it is

The fact that you see "e7ze6110ca pistons (1987 Mustang); that would lead me to declare the motor to be a 302 incorporated in more than likely a 1978 block. You can eliminate 351 Windsor because of the piston #.

Like Mustang 5L5 said, the timing cover could have been transplanted onto the older 1978 block. From the data you've given, I bet that it was a rebuild motor that was probably honed out, re-ringed and re-assembled. If you get inside the intake you will probably see that they either converted it to a roller motor, if so you'll see a lifter spider (retainer) in the motor valley and the lifters will be roller type. Or, they could have left it flat tappet, and your lifter won't be roller type. Either way, you are looking at a 302 Windsor block.

What other data can you give?
 
Measure the stroke to confirm. 3" is a 302, and 3.5" is a 351.

87+ piston, 85+ timing cover (prob EFI).

The block being a 1978 confuses me. I'd grab a wire brush and check the area by the driver's side header for a ford engineering part number. I'd bet $1 you'd find an E7 engineering number.

I'm starting to lean that it's a normal 87+ 5.0.

Measuring the bore with calipers would give a good indication if it's been rebuilt. Stock is 4.00".
