Is this a 351 Boss Engine?

[bobdalogger]

Hold on Steven, DOAE-L blocks came in 2 AND 4 bolt main configurations. Let's see a posted pic of the lower end first. Also, it was not mentioned if it was a bare block or short block. I'd like to see the rods and pistons. Those are Boss-only items.

In that case gxr02190, what do I know? Obviously, I've never been a big Cleveland fan.

My reply was not meant to be snappy. Apparently you know quite a bit. I enjoy reading your informative posts. You have a lot if insight.

Pardon my skepticism, but Ford built 1,806 Boss 351 mustangs. Approximately 550 of those are accounted for to this day. So that leaves approx. 1,250 un-accounted for. Out of those, I would have to guess that almost all of them were either crashed or rotted away and were crushed years ago. Yes, I said crushed. And no, not all of them had their engines removed before they were crushed. Back then, they were just another worn-out or damaged car. Of course, Ford made more Boss 351 engines than cars - they had to - for warranty purposes, but there aren't that many to mention. I'm sure not all of those are lurking in garages somewhere waiting to sprout up like daisies for some lucky mustang enthusiast.

Here are some pictures of some pictures i took in 1987 when i pulled it apart and found 2 broken cylinder heads...(maybe thats why it was removed from the car??)

bobdalogger, post a pic of the bottom end. Curious to see if it has 4-bolt main bearing caps.

here is a picture of the engine now...
I have it on the cherry picker i will pull the pan this weekend..
I seem to remember it had 4 bolt mains in 87 when i had it apart and replaced the main bearings...unfortunately i didn't take a picture of the bottom end at that time...
