Where can i get a cobra Motor

Built 2v flows well enough to compete with stock head 4v. Remember...even after 4v motor you're gonna need a fuel system to support it in the long run, and alot of other little junk. Until 4v headswaps become more affordable (hellllooo aftermarket performance parts manufacts.??) or my motor pops without any warning...I'll be staying 2v. Once you get over 600hp the motors start to even out...that is until the 800hp range, then the 4v takes it.

But like everyone else has said, eBay, forums, local forums, local wanted/for sale ad papers, etc. etc.
