    I have a 350 that i built up and am now choosing a carb. what i really want is the holley truck avenger but can't afford it now. a buddy will give me a 650 holley, 750 holley, or a 850 demon carb /forums/images/graemlins/smirk.gif. which one should i get? i know nothing about the carbs he has other than what they are, as in new or need rebuilt which is fine. /forums/images/graemlins/truck.gif

    What do you plan on doing with your truck ??? If you plan on any crawling, it seams that the Q-jet is the carb of choice. For mudding, I would think a Holley would be fine. I ran a built little 355 small block (300+ HP) with a Holley 600CFM Double Pumper (Mecanical secondarys) carb. So I'd go with the 650.

    In my experience with Holley carbs and off road... you shouldn't use them AT ALL unless it’s that new truck avenger carb. I had a 750 puddle dumper on my 454 and it completely totally unanimously overwhelmingly SUCKED THE BIG ONE. It only took a small bump, and the carb would stumble and die.

    Next I would like to talk on the subject of carburetors. I’ll only say it once. If you are going to spend ANYTHING for a carb… save your money and get fuel injection. Ask anyone here that has gone from a carb to EFI. I am in the process of buying an EFI system from www.customefis.com for my truck. He has systems for the SBC that run around $840 complete. Please please please, do some research before you spend your money on a carb. I’ve learned my lesson, and it only cost me $550 for the money I lost on my Edelbrock 1910 carb. /forums/images/graemlins/frown.gif

    Just my .02!
