I say the Holley Truck Avenger, don't use your current wore out Holley as a basis to call them junk...did you buy your current carb new, or was it someone elses problem that you got stuck with. Any carb after it gets so old that the main rod bushings wear so much that it starts to leak fuel and air will cause you many problems. I like the Edlebrock for a street carb that you don't want to have the ability to tune it, they work good out of the box (as does the new TA), but the Holley has better upgradeability. The Edlebrock I had on a Heep ran great until you hit the brakes and turned, or put in on an incline..it would die. Some of my buddies have even put the spring kit in the needle valve and still have problems. Now the Holley as with many carbs don't like extreme angles..you need EFI for that, but I would put a NEW Holley if I used a carb. For the Quadrajet suggestion, I 2nd that they work better than the Holley or Edlebrock on angles, but you are taking a larger rear barrel carb and trying to adapt it to an intake with small rear barrels...now for a Chevy, these work great because the intake is designed for them, but on a Ford or any square bore intake I like using a square bore carb...it seems to run a little better.. I figure it is kinda like puttin a 4 barrel carb on a 2 barrel intake with an adapter...not quite that extreme, but you understand what I am trying to say... Hope this helps muddy the water a bit...LOL!
