Engine Block stamp???

i recently bought what i think is a Ford 302 i know for a fact it is a roller block because of the XXX stamped in the valley below the intake and those didn't come out till 1985.. but other than that i have no idea it may not even be a 302... the stamp that i see is FKSE can someone please direct me to what year and ford engine this is? thank you in advance

I am BRONCO man but also a 5.0 enthusiast Street Performance 302 engine build for a future Fox Body transplant in the works

"XXX" does not mean roller block. Non-roller blocks also had that casting mark. It means nothing.

FKSE is not a valid engineering number. (The "K" is not actually a K.) Check it again. It's probably a "F1SE". The F1SE block is very common, and it is indeed a roller block. It was originally engineered for a 1991 Thunderbird (F1S = 1991 Thunderbird) but it was used in other models. The '91+ Mustang also used that block.

If you want to know exactly what vehicle the block came from, you need to locate the partial VIN that is stamped on the flat pad on the top-rear, right behind where the (lower) intake would bolt down.

Fox: I'm having a hard time trying to id what I have. I too have XXX under the intake (and just one X on the other side) and found this older thread thinking the X's may mean something. (My current thread is: "1980 V8 - what is it?").

Anyway, the numbers I see stamped on that flat plate at the rear of my bock are: BB 13808. The last 08 is very faint, and may be wrong. But the BB, then a space, then 138 is quite distinct. If you could point me in the right direction with this and the other numbers I've listed in my thread, I'd appreciate it!

If you're reading that number corrrectly, it is a block that was originally from the 38,08_ 1981 Ford LTD produced at Oakville Assembly Complex (Ontario, Canada).

I also just bought a 5.0 for my mustang and it has F1SE stamped but I got no intake with it and was told its a H.O. Engine. How can I tell what year and model its from?

There are no markings, the only thing I found is right by the starter and it is 1F7 right by the F1SE
