If you look into the intake(were the carb would be) you will see the difference between the two. A single plane has one big area under the carb where the fuel and air mix. A dual plane has two different areas underneith the carb. One "plane" feeds the right bank of cylinders and the other "plane" feeds the left. Dual plane intakes are good at making low end torque.(what gets a car moving from a dead stop)Single planes intakes do better at giving you more horsepower up high in the RPM range and usually hurt low end torque. I have heard that a very good comprimise between the two is the Edelbrock "Air Gap" intake however I have never used one.

They'll have a plenum that is not as deep as an equivalent dual-plane intake. A dual-plane has the runners at different levels - on a V8, four at the higher level & 4 at the lower - which feed from the plenum in basically a 2-story architecture. Generally a dual-plane will have longer runners that curve more than the single-plane, whose runners are shorter & more direct. Single-planes tend to be taller at the carb mounting flange. Dual-planes tend to make more bottom-end & midrange power than single-planes, which are generally biased more towards higher-RPM power. For an engine operating under say 5000 RPM, and anything "stock", I'd go with a dual-plane.

All BB Mopar intakes are "Air-Gap" manifolds. he RPM manifold is a very nice piece. A little taller than stock- so check to make sure you have room- but better low end torque & fuel economy (at least I noticed better #'s) than a stock unit. 1968 Plymouth Fury III 4-Door: 12.79 @ 115, 60'- 1.93 (Hey... it's a Cruise ship... what do you expect?!)

I have one on my 440 in my mud racer and it runs great! I would also recommend the Lunatti Voodoo Cam if you want to add a little rumble to it. The one I have is 234/242duration 513/533 lift,Hyd cam part number LUN-60304LK. This cam is good up to 6400RPM and you don't need a big stall to run it. Our rules limit us to running hyd cams and people swore I was running a roller. This is a good combo along with a Demon Sizzler TQ.This cam also pulls good vacuum for street use. I won 11 races and was 2007 Ky Points champion in My class, and first ever Dodge to win the points in Ky. Hopefully this helps! Good Luck and GO MOPAR!!!!

(440) There are good intakes for a STOCK motor in both designs .... Single plane ? ... Streetmaster. Dual plane ? .. SP2P.
