Decoding a motor...

I found an old motor. I believe it is a 351W. I found some numbers on the block:
E4AE-6015-FA-2
And below those was a little tag screwed into the block with the numbers:
4L15

If anyone has any info on figuring out motor codes, I'd appreciate it.

Thanks.

I'll get back to you with that tomorrow. The engine is at a friends house sitting in his yard.
I doubt more than six. But I'll let you know tomorrow.
Thanks for the reply.

Yep, there's only 6 bolts holding the valve covers down. And it has a two barrel intake.

Thanks for the info. You're right about it looking like a 302. I wasn't sure till I found the sticker on the valve cover and it said "5.8" on it.
I'm guessing it came out of a truck. Ford didn't really put the 351 in anything else but trucks in 1984 did they?

Actually it was November 15th/84
L is for November
M is for December.
Ford doesn't use the *I* in coding.

I am looking at a 79 half ton with a 351. I don't know if it's a M or W. How many bolts in the valve cover on a 351M? What other checks are there?
