I got this idea from conversation in another thread

What do you feel is the baddest factory produced long block set-up.
Im not looking for what CAN be built....looking for PRODUCTION!
A motor that you could change the cam(s), or upgrade the blower, or add a turbo to, put a pile of spray on, or all of them and know that its not ready to bust the seams at 4-500hp. Doesnt have to be a Ford or Chebby, could even be an import. Accessible to the average man, no exotic million dollar junk.

Let hear it!!!
