Carb - Holly or Edelbrock?
As fate will have it my wife smashed our Pontiac Vibe all to bits (no one was hurt) and I'm going to have some insurance money passing through my hands in a few days. I think I can manage to filter off enough for a new carb (be very very quite) :).
Should I get a new Holley or Edelbrock ? What would you get? Thanks, Joe. |
for your truck, holley, im not saying edel is a bad carb, but holley is better suited for track, imo
depending on gears you have maybe mechanical secondarys there are many good holley based carbs demon,quickfuel,proform, and i think summit has their own branded holley |
Holley double pumper..
|
Stock 340/727 3.55 gears
I went through Holley's carb application guide and it came up with this guy http://www.holley.com/0-81570 your thoughts ? Thanks Joe. |
Race track, Holley. Daily drive, Edelbrock.
|
I hve a Holley 570 Street Avenger Carb I like it and runs great.

Edel should be fine with a stock motor but if you plan to cam it up the Holley works better. I will never buy an Edelbrock again.

Since you seem to be making trips down the 1320, the double pumpers will get you off the line quicker, it your tires can hold. I've "heard" a lot of good things about the Edlebrocks, but there's something about two squirts of gas that's hard to argue with. I'd guess that Holley Vac secondary or an Edlebrock, would be better for more of a daily driver / cruiser. Archer |
Thanks guys.
The Holley web site pointed me to the 570 cfm Street Avenger 'Vacuum Secondary'. Seems the Mechanical Secondary is for lighter vehicles? I have an idea from my experience with my Carter how the vacuum secondary works, but no nothing about a mechanical secondary although it sounds interesting. Anyone no the difference? Than you. Joe. |
Checked out the Demon carbs?
|
mechanical secondaries are just that, they dont rely on vacuum to open the secondaries, they are better for lighter cars/trucks i wouldnt see anything wrong with a mecanical for your truck. with 355 gears, maybe others will say diff? how much does you truck weight?
|
I prefer mechanicals for sticks, and vacuum for autos. JMHO. Do not confuse me with an expert.

First I'm hearing about DP'ers only for "light" cars. The Charger is 4200# with me in it and when I switched to a DPer I lost 1/2 second on the quarter. There was a noticeable difference off the line. The trick is to get the right size carb (cfm) and jet it correctly for your engine/truck so it doesn't bog when the bores open up. I guess YMMV.

IMO, Edlebrocks are S**T. I'll NEVER run one. Holley 4 lyfe. On a serious note: My car ran WAY WAY WAY better with a the Holley 650 double pumper over the Holley 650 vac secondary. Guess we all have opinions on motors. I would only run a 650 DP on just about anything and mess jet down with a smaller motor. My carb is EXACTLY the same as it was when it was on my 340. No changes. Both motors ran very well. |

"Dual feed fuel inlet" it is also described as "Vacuum secondaries". Is dual feed inlet the same as double pumper ? Thanks Joe. |

Most Holleys have two fuel bowls and require two fuel feeder lines (or usually one line with a splitter). The difference is how the fuel gets from the bowls to the bores. The both the DPs and vacs have a pump on the primary side, but only the DPs have a pump for the secondaries. The vacs use a vacuum diaphragm to get the fuel into the secondary bores. See if this helps: http://www.youtube.com/watch?v=INmSG7uWuYo Archer |
I just read Archer's post and he may be on to something.

Thank you Archer for the video link. Very nice!
I can see now through recommendations and this video that the double pumper and mechanical secondaries are the way I would like to go. Looks like this will add new meaning to "give it the gas" :) Thanks again everyone. Joe. |
I have heard that with Edelbrock carbs and mopars get along really well. My challenger has a 1406 edelbrock on it. But then again a holley double pumper on the track would probably be the way to go. So I'm going to agree with the majority here and say holley on the track and edelbrock on the road.

Will I managed to skim enough off the top to get a "new" Holley 650 CFM double pumper with mechanical secondaries, Part# 0-4777C. Got it off ebay at a rather discounted price.
Racing at the nearby track is over after this weekend so I won't get down to race till next year. However they do have three weekdays for testing in October :) Thanks guys for your tips and advise, if I get a good hole shot out of this deal I promise to post a video :D |
sweet keep us posted!
i sometimes get a sinking feeling when i buy from ebay, only been burned once thus far. |
