Yes. It really depends on what 'type' of injection system you want and how much money you have to spend. As DB stated, there are simple "bolt-on" systems complete with necessary electronics and wiring available; but they can be expensive, compared to using salvaged Chevy stuff from later vintage. On the other hand, spending less on the used stuff will create a lot more work on pulling together all the stuff/info/programming that is needed to make that system work correctly. Either way will work for you, it just depends on your needs.
