i actually am about to do the fuel injection for my 82 i called and talked to John in tech and he said that the best way to do it is to get kit number three because kits one and two dont come with the ignition and you would need to get a msd box and one of there distributors to run it but he said also that it is really easy to tune and you have a fine tune adjuster on the dash so if you are driving down the road and want better mileage you can lean it out some after talking to him i feel really good about buying it but it is a bit of money hope this helps
