    Pretty heavily weighted toward Holley?

    I run a Holley now (but on a 302 Ford) and prefer them. But, I had a Demnon 2 bbl on an AMC straight 6 and it was really nice. My current SBC (still on the stand) will prolly get a Holley or two.

    I like Holleys. Have a complete set of jets and power valves which helps a lot in super tuning them. Also use
    Edelbrocks, which have been maintainence-free.

    Demon, not the cool square one, but the one that looks like a Holley double pumper
     
  8. Who did I leave out ?

    Maybe I can edit for you

    On a stock small block 327/300 HP I run a 450 Holley VS.
     
  11. My 327/300 came with a AFB Carter ( 3721SB ) which works
    Great on it.!

    Just my 3.5 cents

    I had a Holley 600 DP instead of a 650 on a 327 so I voted 650.

  13. One overlooked point; this poll ignores what the vehicle is used for.:confused:

    I had a Carter AFB in a street-only '55 Chevy and have an Eddy 650 in a '28 Ford Tudor.
    If they were race cars or tow vehicles, I might've chosen other options.

    I like Holleys.....;)
     
  16. Ive been running a Rochester 2GC tri power the last few years and it's been very reliable, good gas mileage and looks good also.

    I like to call Holley’s Dickwith carbs.
    Everyone I knew that had them was always Dickin’ with them. Change jets, change accelerator pump, Take off the float bowls again.
    Just teasing the Holley guys.
    I run Carter AFB’s on everything. Originals, not the current copies.

    I don't know that you've left anything out, but you have 8 different Holley options, one Rochester and one Edelbrock. I am happy with my Edelbrock.

    My experience, using 350 as example. 327, 383, 400 may adjust up or down a bit on cfm, but vacuum vs mechanical secondary recommendation holds.

    Driver, street engine - Q-Jet or Edelbrock (carter)

    Mild performance (up to 460 lift, 260 duration, where youre still on a factory stall speed) - 650 vacuum holley, or tuned Q-Jet / Edelbrock.

    Street performance ( 470 - 490 lift 270- 280 duration, mild stall, decent gear. 650 double pumper, lot of guys use 750 here, throttle response with 650 is much better and this is still mainly a fun driver. Power band on those cams go up to 6K rpm but heads on these builds probably dont support much more.

    Street strip ( .500 lift, 3000 stall or more and deep gears, good geads) 750 double pumper, no reason to go larger than 750 on SBC until you get into BIG heads, large strokers or dedicated race set ups. 750 DP can be tuned to take all kinds of load.

    Ive only run one of the edelbrock carbs, like it, for a driver theyre really nice, finding good rebuildable quadrajets isnt as easy as it used to be.

  21. I’ve had Holley, Edelbrock and Quadra-Jets. Had good service from all three, but currently would choose an Edelbrock.

    I've been a Holley buyer for 50 years, and I use them on everything I own. Mainly because I know them, and what they need to work. And I can usually fix any issues on the side of the road if something happens. And I've got a ton of spare parts for Holley style carbs here.

    My gasser runs twin Holley carbs on a Holley Pro Dominator tunnel ram. They are 450 cfm, and have a ton of modifications done to make them what I wanted. 350SBC
    My daily driver '69 Suburban uses a 600cfm vacuum secondary Holley that's 100% stock, and just bolted on and tuned. 350 SBC
    My '39 Chev coupe uses a Quick Fuel 650 DP carb on the 350 full roller motor. Nothing done to it, except tuning also. But I am running it on an Edelbrock Performer RPM, and using a 2" phenolic spacer under it to gain some high rpm performance.

  23. 71BB427,
    Did you cut down
    Plenum divider
    on Performer RPM ?

    Or did the spacer take care of cutting plenum divider ?

    I'd say that the key is what you know and are comfortable working on. I used to run Holley on my 48 and a couple of other rigs. I've still got a spread bore Holley hanging on a nail in the garage that I made two trips to Texas with. Once on my 48 an once on the 70 C10 that I had put together for my son.
    I had played with that carb to no end an had put center pivot float bowls on it so no one who eyeballed it knew what it was.
    My buddy hated Holleys and one time I found one in the bed of my truck after I got home from his place that he had stuck there.
    I had a 650 Edelbrock on my last 350 and it was a great carb right out of the box I didn't have to do much adjusting when I put it on and ran it until the engine got tired. It may get stuck on the 4 barrel intake on my 292 six just because I have it.
    My 454 in the dualie has a Q jet that works great after I rebuilt it. I've got a correct Q jet to rebuild to put on the Cad 500 in my other "late model" 71 GMC.

    It still comes down to what you are comfortable working on plus what works best for what you are doing with the engine in the vehicle that it is in. Daily driver V8 with 300 and something cubes it is hard to argue with an Edelbrock AFB or a well set up Q jet for drive it and don't fuss with it. Trying to get a few more tenths at the strip with a strong street engine, I'll go with Holley every time.
