Best Carb for Combo?

[gork1rogues]

Hey, I'm trying to decide which carburetor I should use with my combination, I have a Holley 650 Single Pumper List6520 or can get an Edelbrock 600 #1406 for around $200 or I have another 600 Holley Single Pumper but it is in need of tuning and a rebuild

My combo consists of:
86 Block With Flattoppistons
86 GT Cam
Ported E7 Heads with larger valves
Weiand 180 2P intake
1.7 R/Rs giving a valve lift of .477
Heddman Shorty Headers

Just wondering if I should stick with the Holley or go with the Edelbrock or would it not be worth it at all?

The Holley was probably bought sometime in the 80s and put on a shelf, it has some dust on it but still has original black marker marks on it, probably would put a rebuild kit in it if I used it.

I prefer the edelbrock carb the holley isnt as good for street performance as the edelbrock, but the edelbrock has pefrmance but still gave me better gas mileage then my old holley double pumper just my opinion so do what you want

i would go with the edelbrock but then again i am a edelbrock person but still i mean i got better mileage then my buddy that had a holley and my car was faster too and it was the same setup in each car

If you know how to tune a carb, go with a Holley.......I wouldn't touch an Edelbrock.

Ditch both and buy my BG Speed Demon 650 Vac Sec. carb

my preference is holley you can tune every aspect individually, but out of the box edelbrock is better for idle and low speed operation and are more trouble free. also id never ever use a stock edelbrock for a high performace application, i have a friend that has burn a hole in a piston and still uses the damn thing wont buy a holley.

yea on my old 84gt i threw on a 600 cfm edelbrock and it didnt need no tuning what so ever.

but i would think that since you have those mods i would go with a 650 double pumper.

allright, i think i'm going to throw a rebuild kit in the holleys and give both of them a try, thanks for the suggestions

i dont mean to bud in but what carb would be good for this combo

performer 5.0 heads
performer rpm intake
e303 cam

 

[ashford]

probably a street avenger

 

[maverick0716]

Street avenger carbs are just glorified vacuum secondary Holleys with a few added features like clear site plugs and quick change secondary spring access......if you want the most power go with a 650 double pumper with that Performer RPM combo

i dont really know how to tune a carb though. is it hard?

Go Barry Grant Speed Demon. I just bolted one of these on my car and it's awesome. My combo is very close to yours
