How many of you do not have their original engines and wish they did?

I thought of an idea of tracking down our original engines for our trucks that do not have them. What if all of us who still have our original titles with the original engine numbers on them posted the number here and see if by some strange chance, someone here may have it in their truck now?
or vise versa, post the number from your non original engine and see if the truck it came out of is still around.
I think it will be kind of cool to see if this works.
My GMC engine number on my title reads:
24830729

The number from the engine in it now reads:248240236

It might be worth a shot
