2 X 4 setup

    Hi Everyone,


    Just wanting some thoughts on the dealer options 2 X 4 setup (Holley carbs).


    1. Do they increase horsepower significantly


    2. Any setup issues - tuning etc


    3. How do they affect the way the car drives?


    4. Any other thoughts!


    thanks,

    1) Ford dyno tests showed 30hp, IIRC

    2) The original 289 linkage was straight line. Depending on your setup unless you had some gears or RPM's some bogging could occur. If you rotate the carbs and use the big block linkage the carbs are now progressive and is much easier to tune.

    3-4) Great fun! I have Holley's on my 65 (preparing to convert to BB linkage). Also had a Carter setup on a 65 Hipo. Looks cool when you raise the hood.<img src=images/icon_smile_cool.gif border=0 align=middle>
