You have to take the engine apart to see if it's a reinforced 428cj block. There may be a way, but I doubt it. (for ex, the reverse 501 block is supposed to be reinforced, so if you see a mirror image 501 where the 352 is supposed to be, your block should be reinforced. I'm not sure about this, but that's how I understand it.)

You can get the casting number from the heads. It's between the center spark plugs (between 2&3 or 5&6). If it says, C80E 6090N, you've got 428CJ heads. If it says something else, post the number and someone will look it up.

If you drop the pan, you can find out a lot. The CJ had extra ribs along the main webbing. It's pretty suttle, so you need to see a picture to know what you're looking for. The CJ rods have larger rod bolts (11/32 I think). I don't know the pn's, but you probably can't see them by just dropping the pan, anyway.

I'm rambling now, so I'll shut up.
