I have a fuel distributor for my 77 450SL lying around(see attached pic) that has been removed and the correct fuel distributor(non-lambda)reinstalled. The distributor is in excellent working condition and I was wondering is it possible to convert my standard CIS system to lambda and if so, what are the benefits and or negatives. I notice there is an extra port that I did have blocked off(#1) and cap screw on top(#2) what are they for? I have read from my CD ther is a lambda valve and electronic controller that works with a Oxygen sensor. Are ther other things I would have to modify?

Thanks in advance
