Monojet thoughts
 

Started rebuilding the stock Monojet on my 69 C10 (I6-250) last night, with a great kit from Mike's Carburetor Parts, so far so good, it was filthy inside and out so it's getting a good long soak. Anyway, as I was preparing to do all this, I did a bit of research and while over at the Stovebolt site I read that in their opinion a two carb progressive system is really optimal for the I6 engines. My understanding is that it compensates for some of the limitations of the original single barrel carbs shortcomings at low speeds. At this point I'm going to finish my rebuild and reinstall what I have, but what are everyones thought on a future upgrade to run a two carb progressive set up or even a two barrel carb, which I'm guessing falls somewhere between option 1 & option 2? I'm looking for a solid daily driver that runs well and as efficent as possible, not a 1/4 mile beast. Thanks and I look forward to the insights.

I think the monojet is just fine for a mostly stock daily driver. Just keep an extra fuel filter in the glove box. If it were me I'd save my time and money for something else. I always thought my K20 was pretty good on gas for what it was. I hauled firewood, dirt, gravel, mulch and pulled trailers and I thought it had enough power. The 67 was heavier and had 4.57 gears and it did better on gas than my 72 C10 which had a 350 and 3.73s.

It all depends on what you want out of your truck. If you're looking for better mpg the extra carburetion probably won't do it but you will get slightly better performance. My 68 GMC has plenty of zip with the mono for highway driving and the little hauling I do.
