Q & A

What's in the Box

In the '60s, if you wanted to have the baddest car in town, you needed to have dual quads under the hood. These intakes accept Edelbrock carbs and make power in the 1500-6500 RPM range. For Small Block Chevy V8s with 1996 and later Vortec (L31) cast iron or the Edelbrock E-Tec aluminum heads.

  • Low profile for hood clearance on most vehicles
  • Air-conditioning bosses and front oil filler tube boss included
  • Stock alternator brackets do not fit
  • H.E.I. distributor will fit
  • An external water bypass boss is machined into the front of the water crossover for use on 1996 and later Vortec production engines
  • Carburetor Recommendations: Edelbrock Thunder Series AVS carb #1803 and #1804, 500 cfm

OTB Gear 4451 Full Fin Air Cleaner, Offset Base, Polished
SKU-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.
