Thread: lowrise dual quad 350 sbc horsepower???

that dual setup is fine...those will work on a stock 350 if you set the carbs right...just jet them down....I have used this same app before and know it will work....It will idle high though...I would also use a 4 hole phenolic spacer under the carbs. A one inch will do....

I would suggest using the Edelbrock 500cfm carbs though because of port velocity and just convert them to electric choke....

These intakes are good for 425hp without mods. These intakes are a very good flow design and do better than most think while still maintaining slow speed torque!

I do run these on a 1to1 ratio (running on both carbs equally) and chokes on both carbs for my customers....
