Q & A

What's in the Box

There is nothing sweeter looking or sounding than a dual quad on a Chevy!  This one kit gets you two manual choke Edelbrock carbs, an Edelbrock unpolished intake manifold, fuel line and special progressive linkage.  Just add a suggested air cleaner to finish your installation. Will clear HEI distributors. 6-7/16" carb centers. 

  • 1957-86 262-400 small block
  • (2) 500 cfm manual choke carbs
  • C-26 Dual-Quad manifold
  • 1500-5000 rpm
  • Low profile for hood clearance on most vehicles

Notes

  1. Electric choke-equipped carburetors will not work on this 2-carb setup. Electric chokes will not release fast enough, causing the engine to load up, foul plugs, and stall before the choke fully opens. With manual chokes the driver can open the chokes as soon as necessary after the engine starts. (With the huge fuel supply available from two 4-barrel carburetors, a choke mechanism is really not necessary but for a brief time.)
  2. Air-conditioning bosses and front oil filler tube boss included.
  3. Stock alternator brackets do not fit.
  4. Port exit dimensions: 1.18" x 1.90".

Specs

Measurements using the rear valley of the intake as a starting point it is:

  • 3.433" to the bottom mounting surface
  • 6.640" to the ring mount on the carb
  • 7.553" to the top of the throat/highest point on the carb
Measurements from the bottom of the intake valley to the highest point on some of our popular air filter assemblies:
  • 325-4237: 10.490"
  • 325-1235: 9.753"
  • 325-4119: 11.489"

No this will not fit on The GM crate engine 35519210007 which is the 350 with 330 hp. That engine requires a Vortec style intake manifold. You would need dual quad kit 92519916 for that engine but that intake does not have the provision for a oil filler pipe.

For a basic bracket and return springs 491SRK4000 or 49141000 in black works well. Then you will need a throttle cable such as 4911000U and a kickdown cable 491KD2700U. Since you are using Edelbrock carbs you also have the option of using the cable bracket 491105 instead of the basic one.

We offer the carbs in the Endurashine finish which we can substitute in this kit for the difference in the cost of the carbs. Sorry we do not offer the intake in an Endurashine finish.

What about a PCV setup This kit is going on a 67 or 68 327 in a 60 corvette. I would like to retain the corvette valve covers that do not have pcv breather holes in them. Does the intake have a hole that can be used to install a pcv valve and connect it to the carb to complete the pcv system (using the oil fill tube as the air intake)?

The intake in this dual quad kit has a hole for the draft/fill tube port. There is no hole in the intake to accommodate the PCV valve. You many consider the end of the valve cover where it could be drilled out for the PCV valve.

You can use a choke cable such as 91126114 and then link the two choke arms on the carburetors together so that only one cable is needed.

The earlier SBC engines had an oil filler tube in the intake maifold. You can plug that hole with a soft plug since it is not needed on your 78 Camaro. Sorry I do not offer this dual quad intake in an Air Gap version.

This will clear an HEI distributor. The small block dual quad set up number 92519906 could be used on your 350 engine as long as you have the early style heads from 57-86. We also offer a similar kit for the Vortec style heads under number 91619916. The carb centers are 6 7/16” and comes with adjustable progressive linkage.

This Edelbrock dual quad set up will bolt directly on 1957-'86 small bock chevy's. It will run on most applications with our standard fuel pump pre set at 7 PSI and delivering 67 GPH. If you run a higher flow and higher pressure pump you will also need to run a pressure regulator to eliminate the high pressure forcing fuel past the needle and seat. Adding headers, a high performance cam and cylinder head work will aid in the performance of this dual carb set up.

The fuel log in the kit is 3/8” and 3/8” fuel line should be sufficient for even high rpm applications. The 7 psi fuel pump by Holley or Speedway offering 97 GPH should handle the needs without a regulator.

OTB Gear 4451 Full Fin Air Cleaner, Offset Base, Polished
(Part #2474451)
                        Have you got twin 4's with really tight spacing? The selection of air cleaners for you has been pretty slim right? Many manifolds out there position the carbs with only 6-7/16" center to center. This assembly features a 1/4" offset base to deal with this problem - a simple solution to an old issue. We use our Platinum Series air filter with A-356 aircraft grade castings for a show quality product. The filter media is a medium gray, washable oiled cloth. Hardware furnished includes a polished stainless socket drive top screw. Diameter 6-3/4" - Height 4-1/8". Fits carbs with the typical 5" base.
Priced and sold as single assembly - purchase 2 for a twin carb application.

OTB Gear 4461 Orbit Style Air Cleaner, Offset Base, Polished
(Part #2474461)
                        
The inspiration for "Orbit" came from the the '30's - '40's Ford horn button design. But repeating rings were a very popular design theme by a number of auto builders. Got twin 4's with real tight spacing? The selection of air cleaners for you has been pretty slim, right? Many manifolds out there position the carbs with only 6-7/16" center to center. This variation features a 1/4" offset base to deal with this problem - a simple solution to an old issue. If spacing this tight isn't your problem, we have a straight base also. If running twin carbs, check your center to center spacing. We use our Platinum Series air filter with A-356 aircraft grade castings for a show quality product. The filter media is a medium gray, washable oiled cloth. Prefer to have an unpolished finish? You can have that too. Hardware furnished includes a polished stainless socket drive top screw.
