i haved read a couple of article about puting a 87-93 fuel injected 5.0 in a classic mustang. i am very confused they lack some of the little deatials and each one told me different. i was wondering if anyone knew were i can buy a book in print that explains doing this conversion any help would be greatly appreciated.

 

You may want to consider putting on a carbureted version of a 302 first, then upgrade to EFI later. But, going straight to the EFI conversion has been done. If you do some research, you will come up with a ton of information. Here is one such article.
