does it come with a computer for the ignition?

 

Welcome to FTE! Computers in cars were a pipe dream back then.

 

Computers were sciencefiction back then, but I believe you mean electronic ignition. The answer is yes and no, early production models had conventional points and later prodution models had early duraspark electronic ignition. I'm not sure the production date switch, but if you have the later one there will be a silver or black module (approx. 6''x3'') on the top of the left inner wheel well under the hood. also a white plastic collar on the front of your ignition coil for diagn. tach hook up. '75 on are all electronic ign.
