Q & A

What's in the Box

The Thunder Series' unique Qwik-Tune Secondary Air Valve allows for limitless calibration of the secondary circuit with simple hand tools while on your vehicle. It can be easily adjusted, in seconds, to suit your application - no extra parts required to achieve optimum performance.

Designed and calibrated for optimum street performance in small-block and some big-block engines. This four barrel carb matches with a variety of manifolds that include Edelbrock Performer, Performer EPS, Performer RPM, RPM Air-Gap, Torker II and other brands of similar design.

  • Primary and secondary booster clusters offer the most accurate and up-to-date calibration available for today's fuels and octane levels
  • Edelbrock carburetors bolt on and run right out of the box
  • Float levels are factory set; adjustments are rarely needed
  • Change jets, adjust floats & replace needles/seats without draining fuel or removing carb
  • Two-piece design means no gaskets below the fuel level for leak-free operation

A carb bracket such as number 491104 will house both the throttle and the kick down cables. The arms on the 3251806 will accept the Lokar cable kits also. Or you can use the Lokar bracket number 491SRK4000 along with the cable kit 4911000HT-24 and the kick down cable such as 4912350HT and the three parts bolt together and offer the same end result.

Will this fit on your dual plane Typhoon manifold that comes with the 383 motor, #915-32383? Will I need an adaptor? What carb spacer do you recommend? I`d like to raise it a litter and help keep the heat down. What Edelbrock mechanical fuel pump do you recommend?

Yes this carburetor will bolt right to the Typhoon intake manifold without any adapter needed. We do not recommend a spacer for your application but you could use a 4 hole spacer such as 7202085. I would suggest only using four hole gaskets in order to keep the plenum divider sealed. This will help with low to mid RPM torque, especially at part throttle.

Open the throttle a few times to see if fuel will squirt out. It should squirt fuel when you rotate the throttle. If not and you do have 5 to 6 psi of fuel pressure then the needle and seat may be stuck. Contact our customer service department if you are not able to get fuel to squirt out.
