Hello everyone, sorry I haven't replied in a while but I'm a fire fighter in california and my department sent down a engine to fight some fires down south, so I have been stuck at the station covering. I will look into to overdrive transmission. The question I have now is what does the duel carb do in terms of power. I have a couple of work buddies that say it would be a lot of work for not much gain and it would take some tinkering. Those who have them what are your opinions and how hard was it to sincronize and did you see a difference in power, sound, or fuel eco?
