Ok don't shoot me!

[NickHansen]

Yes I know there are many debates about who's better Eldebrock or Holly..... I just need some advice towards my set up. Ok so for all you performance junkies out there, any one got experience with these carbs? Got it narrowed down to three. The Edelbrock Marine Carburetor 1410 750CFM, the Holley 770 CFM ALUMINUM MARINE AVENGER CARBURETOR, and the AED Performance 750 HM Marine.....so give me the good the bad and the ugly. Looking for ease of setup out of the box and easy long term care and maintenance. Was so going to just do a DP but was told the Elde would be so much easier.

Oh it's going a 400/445 hp/torque 383

The Edelbrock Marine Carburetor 1410 750CFM,

Ayuh,.... I Love the ole Carter AFB carbs, 'n don't do Holleys,...

Holley

You have a motor build thread?

 

[Scott Danforth]

700 cfm is more than the 383 can draw in

 

[alldodge]

Only if it stays within the norm. Increase the rpms and the cfm's go up

 

[Scott Danforth]

Correct, however unless the 383 is spinning over 5800 rpm, it cant draw more than 700 cfm

As far as ease of tuning the Edelbrock is by far the easiest to work on (not that the Holley is hard. The Holley pictured looks like vacuum secondaries. You can get away with a little more CFM with vacuum secondaries but I am speaking from an automotive background where 5000-7000 RPM's is typical. The 3rd one pictured appears to be a customized Holley. I'm sure the cost is up there and probably overkill. Personally I would probably go with the Edelbrock but probably more of a coin toss. What I don't like about either is they are square bore. A properly set up spread bore is more fuel efficient and generally has better throttle response. For that reason I like my q-jets. I had a 1979 GMC 1/2 ton 4x4 with a 350 that I built. I had a q-jet on it and on a whim replaced it with a brand new Edelbrock and could never get the gas mileage out of the Edelbrock that I did with the q-jet. My Holleys I didn't care about fuel mileage so it didn't matter. Most of those were on 500-700HP engines.
