Thread: Edelbrock vs Holley

Tweet

Looking to replace my Summit 750cfm, with a carb that won't flood out my engine, and needs little attention. I have the Edelbrock Performer manifold, Comp Thumper Cam, and Brodix 64cc aluminum heads. The motor is just a 350 crate motor.
Edelbrock 600cfm Performer carb, OR Holley 600cfm Street Performance carb? Would like to hear some feedback from you gents, that have either one of these on your rod. Thanks

Got my Holley off of e-bay for 25$ put a kit in it, been the best carb. i have ever owned.

Either one right out of the box should work fine. IMHO, though, the Holley is a better choice as I believe they are easier to tune, but to use the Holley it will require a spacer/adapter since the Performer is a spread bore manifold and if the Holley is bolted directly to the manifold the fuel signal will be messed up.

i would get the 600 s holley . looks good and performs well. very tunable .

you will find we like them both .. i have a holley on my stang and an edelbrock on my pinto .. the edelbrock presents less problems such as leaks and stuff but may require a pressure regulator as they cant tollerate high fuel pressures .. make sure to get the electric choke model ..

Good advice Hoss. There must be a zillion Eddy's on the street so it just becomes a matter of personal preference.

Almost like the difference between Bud and Coors, personal preference, but in a blind taste test 75% of the die hards get it wrong when guessing which is which! Like my edelbrock, never had to set a thing right out of the box.

The old adage is, " A Holley will win on race day, but an Edelbrock will get you home from the track." Some truth to that IMO. Holleys pump out more HP as the Edelbrocks are a little detuned out of the box and made for smooth street operation. I personally feel Holleys are a little more trouble prone, I know they don't like a speck of dirt in the fuel, whereas an Edelbrock doesn't seem so finicky in that respect.

I like Edelbrocks because you bolt em on and forget them, and the fuel milage is excellent.

Don

how do you know, what thickness phenolic spacer to use under your carb? I've seen 1/2", 1", and 2" spacers in the summit book.

the factory never used more than a 1/4 inch spacer so a 1/2 inch one should be more than enuff ..

x 2 Don, also nice thing about the Edelbrock is you just remove the top to get at stuff, I've tuned a fair few Edelbrocks over the years and they are very tunable and you will get better gas mileage out of a Edelbrock if setup right.

That's a 'Which is better, apples or oranges' question.

For a street driven vehicle, you just cannot, IMO beat that Edelbrock. As roadster32 said, pop the lid off of it, make your changes and then go from there. Holley's - great carb, still fairly easy to tune, but changes require that you dump a cup or so gas every time you go inside. And if it has the exterior feed tube to the back bowl (4160 types), the 'O' rings always need changing when you disassemble for changes or risk a fire(personal experience)

The electric choke version is identical to the manual choke version except for the jetting - it's a step or two leaner and $40-$50 more money

the orings were done away with years ago. they have a rubber sleeve on the tube now. i have never run an out of the box carb. they are at least 2 sizes fat on the tune .

I think Holley is the better but I use both. Ed. one the wifes 57 and Holley on my 73 BBC. I belive that Holley makes them (selles them) on the fat side so people that don't know better wont run them lean...

Friend bought a 290hp crate SBC and just added an Edlebrock out of the box, no issues once set up.
