either the 1850 or 3310- those two carbs will cover the needs of 95% of people out there.

I'm a big fan of the (my) Holley 470,800cfm D.P. I put it on our 70 Chevelle SS 454-550 H.P. It has great responce,burns clean,and there through the gears.

 

Nice ride....

 

Holley Competition Series 9380 850 CFM................




Features

• No choke
• Center hung float bowls
• 30cc Primary accelerator pump
• 50cc Secondary accelerator pump
• Annular-style boosters
• Mechanical secondaries
• Four corner idle system

Used on my 648 HP 468 BB for the occasional trip down the 1/8th mile and lots of street cuising. I personally like the 4 corner idle adjustability. Carb can be seen in the engine pic in my signature.

I've had good luck with several 3310's 750 vac sec square bore Holley. On the other hand my 4779 750 man sec idled rich on any engine that I put it on even after tuning it.

 

I think the best Holley carb is a tunned Holley carb, not like my fat rich running carb..

 

Here is my favorite Halle :

Oops u said Holley not Halle....my bad .

 

Highly modified 750 4150DP. At one point it was a 4779
427 SBC street strip flows about 835cfm now

 

Kind of a toss up between a 600 d.f. d.p. that I ran for years on a small block. I rebuilt it a couple of times but I had that carb since the 80's . The carb is still going strong on a friend's chevelle , that's a good one:thumbsup:

The other one that I'm running now is a 770 street avenger (other than a primary float that took on some gas and lost some of its bouyancy , and was acting like a sticking needle and seat that drove me nuts for a couple of day's ) this carb has been with me a few years now with no other issues , I really like the electric choke and the ease of secondary spring changes, Oh and it shines real nice too Both are 4150's

 

I'm using a list# 1850-3 , 600 VS with a secondary spring kit works great for me.

 

Thanks for the quick replies... Keep the info coming! :thumbsup:

 

I also like the 4779 750cfm DP. Run it on the 302 and used to run one on a 62 Nova drag car. Good all around carb.

 

Holley HP 750 part# 80528-1.

 

406 CI, street/strip auto trans 4:11 gears. 11.40 @ 117 with the old 750 demon.
Just switched to a Holley 4150 950HP built by pro systems from a Demon 750, still dialing it in but love it so far, crisp clean throttle response and great shift recovery. Amazingly the carb was not built for my motor but one close to it, and it works killer. Patrick from Pro systems is the man :thumbsup: .
As a side note, people freak out about the 950 rating, as most that are in the know will tell you it's the perfect carb for larger cube small blocks or smaller ones that will spin, because the 950 rating is fluff. They have larger throttle plates but same venturi as a 750, so they give great throttle response with better top end flow, they are really more like an 830.

 

As I'm sure you know.... a 750 Demon on a Holley flowbench will flow in the 930 range. Demon's are wet flow rated and thats where most make mistakes when sizing.

 

Holley 4150 style, 950 hp, down leg baby!!!!!!!!!!!!!!!!!

 

4779 Its been so good to me over the years I remember the part number

 

4777 650 DP, No complaints.

 

I just had an engine built with a Holley carb. I know it's 800cfm but don't know the exact model.

 

Thanks for the compliments Dennis and Skip.The 70'Chevelle SS is what my wife wanted me to build for her.We showed the car 13 times in 2008 and it won 9 "best-in Show" and "Best Paint in the Show"at Superchevy in Va.She is so proud of it.I do this stuff (restoring rides) as a hobby here at home (except paint) on nights and weekends.This one (Chevelle) took about 2 1/2 years from start to finish.

 

the guys with the Double Pumpers can keep them.. AND pay for the gas..
As for me, the 4053/3310 780/800 cfm single pump, vac secondary works very well on *most* nice street engines... and for a smaller/mild engine, the little 600 works fine!

 

4150. Mechanical secondary double pumper 750cfm. It's on a 388 stroker, 9.5:1 compression, roller cam, AFR heads, approx 500hp/517lb/ft tq. and a four speed with 3:73 gears.
I got the carb. from AED. It doesn't have a choke horn.

 

1850 and 3310- and "Buddy and the Crickets"!

I've had many Holley carbs throughout the years!.....1850, 3310, 4779, 4780, 6210 and my current 80457.....They all performed excellent, just like me!:yes::thumbsup:

 

Holley 3310
750 cfm
vac. secondary

 

#4053, 780 CFM, square bore, vacuum secondaries, dual feed for my 302. Works fine in my book for cruising the highway or street. You just need the right cam and plenty of initial timing.
