I'd be interested to see what people say about this. I have mine blocked off which is what most people do. From my limited understanding, for fuel economy (i guess you are not too bothered if you have 45's) and driveability, ideally there should be vacuum advance but I guess you would have to take a small bore pipe from each inlet tract to average it out especially if you have a lumpy cam. Otherwise the advance will be all over the place on low revs and part throttle. Has anyone had any success with this? You can/could buy an aftermarket distributor with a different advance curve which does away with the vacuum advance but again, i'm guessing this is designed for performance rather than economy or low down driveability. I have just tweaked the maximum advance and springs on my standard distributor. When you say electronic, I guess you are talking about mapped ignition rahter than just electronic ignition? After all that, i'd say just block it off for now! Jeremy
