joker81 Posted October 11, 2012 Share Posted October 11, 2012 Hi, Does anybody have any experience running Weber carbs or Mikuni carbs with an automatic 240z? Can it even be done? At some point i would like to have a stroker build in there...but i plan on keeping the auto tranny so my wife and dad (crippled hand) can drive it once in a while. I have been told by Whitehead performance (Z specialists) that there is no problem having a Stroker with an auto trans but was curious about these higher performance carbs. Thanks Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 12, 2012 Share Posted October 12, 2012 40phh's from LA to PHX in an Autobox 74 Fairlady Z running a 4.11 rear gear... Got 28mpg at a steady 55-65mph Only thing you want to do is get your throttle pedal positioned correctly with the linkage setup, if it's too low to the floor the kickdown will be activated quite a bit. Uh, that may not be a bad thing... Quote Link to comment Share on other sites More sharing options...
joker81 Posted October 12, 2012 Author Share Posted October 12, 2012 Hey Tony, Glad to see an answer from you here. I don't participate in many topics, but i view many of them and i know that you have a lot of knowledge when it comes to these cars, i see you participating in many of the more technical conversations. Is this 74 Z your car? do you mind sharing your setup with me? In other words, what you are saying, Is as long as the carbs are properly installed and tuned the way they should be, they should run fine with an auto? Also bare with me here, i'm not very mechanically inclined, and not always familiar with certain terms, what do you mean exactly when you say "Kickdown will be activated quite a bit"?

Tony D Posted October 13, 2012 Share Posted October 13, 2012 The car is my buddy Jim's. I did the setup while he was in CA, before he moved to AZ. The kickdown modulator had a vacuum switch pot on it that delayed kickdown somewhat, and by adjusting the pedal height, it didn't kick down all the time. Little solace when the guys smogged it in Chandler and it jumped the rollers into the fan and doinked his hood. Quote Link to comment Share on other sites More sharing options...
