Engine Swaps for a '94?
 

I just purchased a '94 s10 that had a 4.3 swapped into it by the previous owner from a newer extreme.
Just throwing a question out to all 4.3 owners: do you find it produces enough power?
If not, what swaps do you recommend? (it's not the original powerplant in there, so I wouldn't feel bad about parting with it so soon)
What's the most ridiculous swap you've heard of, including japanese engines? (please include links, exclude hate mail)

Thanks!
