Default Intake- single or dual plane

How do you match an intake with a cam if you do not use same manufacturer?
How do you know if you can use a single or dual plane? Does a dual provide more air therefor more hp?
Height of intake must be considered due to hood clearances, right?
I am hoping to bump up my 76 L-48 and want to do the job right. [IMG][/IMG] :smash:

Go with a dula plane. Single plane is for upper rpm motors. Cam should be around 245 duration or more at .050 to run a single plane on a 350. The dual plane will give you more low end torque than a single plane

I don't know much about matching up a cam with an intake but you should get a dual plane. Single plane intakes are more for racing application. A single plane requires more RPMs than dual planes do.

I just changed my intake from a single plane (Torker II) to a dual (Performer) along with the cam in an effort to shift the torque curve down into the lower RPM range. I will know on Saturday if it worked. :)

A recent article I read compared a single plane Victor Jr. to a dual plane RPM Air Gap manifold on the same engine. The difference in HP at was very small at about 6300 RPM ( about 10HP I believe ) while the dual plane developed much more torque at the lower RPM's.

The dual plane Air Gap is one beautiful intake !
