How many cui does my engine have?
Hello from Germany!
I have a 1955 F100 and need some parts for the engine. The problem is that I am not exactly sure what engine I have.
The engine code says: C8AM- 6015- B / 19JB
I already know that it's 1969 engine, made in Mexico, 1st version.
But how do I find out about the cui?
Thanks for your help!
Have a nice Sunday!

With a Ford there is no way to tell what motor you have from the casting numbers alone, you have to visually identify what family it belongs to using it's overall size, the shape of the heads, width of the intake, where the thermostat housing is located and which way it's pointed, etc.

The Mexican 302 blocks are generally considered superior to US or Canada made blocks, mostly because they have the larger 289 type main bearing caps.
However they still use the same components as the other 302s, including main bearings etc.

And it's unfortunate that the thing about the main caps being somehow unique to the Mex block, which they are not. The D8VE-A3A block also has the big main caps. Other than the caps, the 68-79 302 blocks are all identical as far as iron content is concerned. All weigh in at 134-136 lbs, including the Mex block.

No telling with many things Ford did. I've got two D8VE blocks now, one's got the big caps, the other doesn't, the only difference is the small cap block's suffix is 3A instead of A3A.

Do you have pictures of the 2 different caps? I have a 65 289, and have no idea whether its caps are "big" or "small"

I do, but cannot post pics here. The big caps are the same width the full height of the cap. The std caps have a very noticable taper to about half the width of the bottom of the cap.

Baddad, is there any difference you can see between the D8VE-A3 and D8VE-A3A blocks? Are they different where the main caps join?
I seem to recall that the 289 Hipo blocks were the same casting as the regular 289s, just fitted with the special caps.
Also, are there casting numbers on the caps themselves? If so, could you post them? I am curious if they are the same basic casting as the Hipo 289 caps (or Mexican ones).

It'll have to wait til this evening, but I had a Mex block and the D8VE's (still got those) all at the same time. The caps are the same. No difference in the blocks either, other than the Mex has got those two bolt bosses on the front and the D8VE's got the crankshaft position sensor boss above the rear main. All weighed the same. The Mex was 136, the D8VE-A3A is 134 (but it's 60 over where the Mex was std) the D8VE-3A was 135, it's 20 over. and has been clearanced for a 347 stroker crank.
