my 1406 has a manual choke not an electric choke!?

hollywood2k Well,'re input has helped tremendously...i have chosen to go with the Edelbrock 14064....600CFM electric choke for this 76 corvette daily driver. I chose the EnduraShine option...i think i'm going to be very pleased...Thanks for all of your help, once again, Hotrodders!!!

cool rockin daddy A few years ago either Car Craft or Chevy High Performace did such a test. They were all very similar in fuel curves at street speeds (rpms) if I remember correctly. The Grant carbs were the "Claw series" I believe.

454C10 It is funny how people have the total opposite experience with the same carb. Crazy world.

I never had a Holley leak anything, air fuel, or dirt. And I do take them apart a few times to replace jets, power valves, squirter's, ect,and drive them daily.

Yes, I could have used a heat insulator but the sticky throttle got on my nerves and I didn't see a cure for that.

I wonder why car magazines don't compare Edelbrock carbs to Holleys carbs using a dyno, dragstrip, or just for mpg. They compare heads, cams, intake, headers, but not different carb brands. I have seen them do a little Holley versus demon but those carbs are very similar. I'm betting that Edelbrock doesn't what a test like that done and puts pressure on the car magazines to NOT do a test like that.

It would be nice to see three different engine levels (mild, moderate, wild) tested with a 750 holley, 750 demon, and 750 edelbrock. But I doubt they will ever do a test like that because it could jeopardize advertising dollars.

Irelands child
Dislike Holleys

Double post - it's the pits when you do that.

Irelands child I have had at least 6 Edelbrock 600 or 750 CFM versions and have found them to be a great carb. The only problems that I have had is dirt. Since the carbs don't make dirt, it had to have come from my fuel system. My solution to the dirt problem is to take off the dinky in-line fuel filter and install a professional racer catridge type.

While the Edelbrocks run well right out of the box, to get optimum performance you have to spend a few hours setting up the various spring rates, jets and metering rods - NBD - part of the process of making a performance engine reach its potential. You need the manual choke version of the tuning kit for enough choices

The carbs that I have used have never been affected by vapor lock, but in all cases but one, I had no carb heat (the one exception was on my ancient F350/460cid) plus I always run a 1" phynolic manifold spacer for isolation from engine heat and performance enhancement (dubious value).

Also, many years ago, I ran a 401 cid Buick Carter carb on my
'53 Ford w/312 - an it ran great. My '64 Grand Prix had a Carter as well - and this car was a bear after a bit of surgery on the secondary air operated throttle plates.

To sum it up, I have sold all my Holley leakers but two, and they will be gone shortly. I got tired of screwing around with float levels, power valves, accelerator pumps and secondary springs and diaphragms, plus leaky(air) throttle shafts and base gaskets. I will agree that for full out competition they work well - I really dislike them for a daily driver.

454C10 I had two Edelbrock carbs on two different engines and they both vapor locked in the summer and they both had sticky accelerator pumps. It seems to me that the aluminum bodies not only cool down quicker but also heat up more. Also, both accelerator pump seals dug into the soft aluminum accelerator pump cylinders, causing the throttles to feel jerky. After less than a year of use, I threw both relatively new carbs in the trash can and bought a couple of holleys and had no more carb problems for the last 5 years.

Edelbrock makes great intakes but they should be embarrassed about that carb. They are selling a cheaply made carb for little money, and in this case, you get what you pay for. It looks like they decided to spend more money on advertisement than building a better carb.

If you don't what a Holley than get a Q-jet. But stay away from edelbrock/carter carbs.

cool rockin daddy John,

Your last line is absolutely great! Killer! That statement about carbs and tuning cuts right to heart of the matter. It could probably be said for a number of things we do in rodding. Well done.

projectjohn I have a 750 cfm edelbrock carb with the electric choke. I have been extremely pleased with the performance with it. Decent fuel mileage, good performance. It is on a mild 454 that was built for a daily driver. If it was me I would go with a carter/edelbrock/q-jet for some heavy street/ light strip performance. But if it is going to only a strip car Holley. Remember that all carbs do the same thing and the difference is in your ability to tune the carb to do what you want.

I have to agree. 426 Street Hemi, 425 HP 409 just to name two of the legendary engines that used the AFB.

cool rockin daddy The company that actually owns Weber is called Magneti Marelli. They have a plant down south where they make the Edelbrock carbs under contract.
