2.8's?

So I have the original 2.8 that came on my DB when I bought it, I screwed with it the other day and got it running, was just full of bad gas from the previous owner. So i was wondering what you guys have done with the old motors after you've done a 6.5 swap? I know several people have mentioned...

i dont have a DB myself.. but i see a LOT of conversions to clone motors...so what do you guys do with your little 2.8s you take off of the Db30s? their perfectly good engines, just underpowered... they have to be good for something
