I believe that Edel & Carter are now made by Webber. I use the 625 Carter(electric choke) on all my cars. They have proven to be better for me for everyday use on a mild SBC engine...Don

Depends on radical your 400 is. If it's a mild street motor, go with the Quadrajet spreadbore on either a stock intake or a "Performer." If you have modified the motor and are running a gear, look into The Holley 3310 or better yet the Barry Grant Demons. The &50 Speed Demon would work. I just replaced a Holley with one and am tickled to death with it.

Carter type throttle shafts leak, metering rods wear out in their main jet bores.
Eldelbrock has solved these problems, thankfully!
Holley, however, has been the most tuneable.
Power valve blowout is now a thing of the past. At least for folks w/stock autos'or daily drivers. Vaccuum secondaries are best; no fun for those who need to know all 4 holes....60c.c./ 100c.c. gas and whatever air mix is really there. now.
Air valve/m-rods springs or diaphrams. 4 barrel doublepumper is my choice!

350ci to400 750.4150 holley

Hello,

My name is Erol and I recently purchased a 1957 Chevy with a 350 SB with Edlebrock Victor Jr manifold, headers, 4 speed manual tranny, 4:11 gears, and a Holley 650. The engine has a radical cam with the following specs

Valve adjustment .026 (int) .028 (exh)
Gross Value Lift .555 (int) .578 (exh)
Tappet lift of .020 295 (int) 305 (exh)
Cam is ground with lobe center separation of 106 degrees.

I know very little about cams, lifters, and carbs.
I am getting very bad gas mileage (like 5 mph) and I can smell a lot of unburnt fuel in the exhaust. Two mechanics that I have taken it to said the carb is leaking badly and untunable.

I am think about replacing it with a new or rebuilt Holley, Edlebrock or Carter 600 CFM but unsure if they will work properly with my cam. I am not looking for race performance just a more drivable economical crusier.

I know the radical cam is the root of my MPH problem but I don't want to spend the money replacing it and lifters since I don't drive it on a daily basis. Any suggestions on best most economical Carburetor to use would be appreciated. Thanks


EB

Have your Holley rebuilt by a qualified rebuilder and have the throttle bushings done if they are bad. One rebuild kit and you should be good to go. Is your Holley so bad it can't be rebuilt?

Cool

Ottomatic777, go over to Arlington and see Harry at Harry's Hot Rods and have him rebuild your carb or replace it. It's close by and he's honest.

However, the new Holley Street Avengers claim the same "out of the box" performance. I know 3 people who use them and swear by them. If you are looking to knock seconds of of your e.t.'s then go with a Holley. Many adjusments can be made to increase throttle response and performance. Holley's are vacuum actuated using diaphrams, so be careful. A simple backfire could blow out your power valve, which will kill your gas mileage and perormance.
Good luck!</strong><hr></blockquote>


Actually all the new holley, come with backfire protection, and they sell a $10 kit to fix the old ones.

I agree with 4Jaw get a Holly it's all in the tuning and the correct size. Heres a site that everyone mite want to check out if you want to know about intakes and carbs. Holly's site has a free manual for tuning and rebuilding their carbs.

<a href="http://victorylibrary.com/mopar/intake-tech-c.htm" target="_blank">http://victorylibrary.com/mopar/intake-tech-c.htm</a>

<a href="http://holley-carburetors.com" target="_blank">http://holley-carburetors.com</a> tells it all on every carb made all the tricks & tuning
Carter and Eldelbrock are the same carb, Eldelbrock fixes them up a little with a different coating.

never ran a holley but have ran edelbrook its a great carb. i just bought one last weekend 1405 and preformer intake. i was fliping through the paperwork and it said the carb with electric choke was setup for peformance and the one with manuel choke was setup for fuel economy or visa versa i've slept since then you might check it out.

I had a 350 chevy where I did the swap from afb to holley. The carter ran good and got fair mileage, but just could not tune out the dreaded stumble off idle. After tuning on the Holley for an hour or two, that engine responded as smooth and crisp as a new digitally controlled fi motor, and made better power on the top end. I will never run another AFB(Carter, Edelbrock etc.)

Try the sites above and I dont think anyone will have any more problems in tuning any carb.
I thing Holly is still the best.

have used all of the above mentioned carbs and find most to be acceptable, however the holley is the most tuneable, but will not tolerate any foreign particals, you must use agood filter. having said that you must use a good filter on all systems
