    Since the OEM Autocraft on my long gone '79 F350 was, I believe, about 500CFM, a 700 on a stock 460 is too much. The Edelbrock 1406 is a 600CFM and was a good replacement on that particular truck. (I did try a Holley 3310, 780 CFM and it shoved gas through that engine about like a flush toilet, especially driving through the Rocky Mountains - thank goodness for THREE gas tanks and 55 gallons)

    I did probably the first 460 install in a pickup in 1970----we used this truck to pull our 30 foot enclosed trailer with our front engine dragster along with etra engine, tools, extra tires'wheels, etc----we ended up running an 850 holley on it as with the smaller carbs we were constantly getting into the seconaries a little on the fuel econ would go to hell---with the 850 we had much larger primaries and could get a lot more pull before we'd start tripping the seconaries---We also had an 800 on one truck but the 850 worked better--

    Several Ford people saw the install and they finally came out with the 460 as an option in 1973. I just recently did an POrshe engine for another shop and one of there guys ( former Ford eng) asked me what ever happened to the devil truck??? I guess it had a repetation that I wasn't aware of---
