I tried searching this on this forum without any luck, so.....
What I'm wondering is what the pro's and cons are behind single and dual pattern cams.
I understand how it works, I just don't understand which cam works best for what circumstances. Several of the manufacturers making cams for FE's have both types, both with decent durations and lifts. I just want to be more educated about the results each produce before I lay down some coin.

 

A dual plane is better for street use, better low end. A single plane is better for wide open throttle, like at the track.

 

I know the good cam producers have tech lines- they'll ask about the powertrain, tire size, intended use, rear end gearing, etc. Then they'll recommend what cam they offer to best suit your needs.

 

You're talking intakes, he' talking cam shafts.

 

My mistake.

Normally a dual pattern cam will idle smoother over a singe pattern at the larger durations. There are some other differences too. Like larger power band. There are some variable lift hyd lifters that have a bleed rate that do not let the the valves open all the way up at idle. This will also help in getting a smooth idle. But this can be shoot down with a radical cam.
