I have a 38 that is about a year old. makes lots of power but is killing me on gas. My carb is clean, works right, and can be put on your truck as soon as you get it. I am open to either a 32/36 or a 34, I dont really care. I would prefer that your carb be in identical condition to mine, but if not i would consider yours and some cash if it needs a rebuild or something.
