best sbc intake

What is the best performing intake for street/strip.Not daily driver just trying to improve performance.It is a 71 350 with flat top pistons.comp 274 xtreme cam,headers,vortec heads.3.73 gears,4-speed.    I would appreciate suggestions thanks phil  

if you're looking for all out power and bottom end isn't really a concern, i'd suggest a single plane like a victor jr.

What intake do you have now? What kind of car is it in?  

It is in a 56 chevy car has pp cyclone intake.I am trying to increase performance.I was thinking maybe a better manifold might increase performance  

The edelbrock performer RPM or weiand air strike manifolds are alot better manifolds then those china made knockoffs.

I would never use a china made part on my engines herd that crap is no good. Just like every thing else made in china.  

I agree 100%.
I have seen power losses with the pp knock off intake.

its not my car so i dont know for sure but my budddy has one on a 383 and it runs very strong. im not sayin its an edelbrock or anything but i wouldnt say that switching is going to get any huge power gains.low end torque maybe because your going from single to double.  

The cyclone and the rpm and air strike manifolds are all dual plane intakes.

maybe i wasnt think of the cyclone, what is the other china knock off. is it the hurricane?  

Cyclone, typhoon and the hurricane and all suck especially the hurricane.

yeah my bad i was mistaken. man you really hate thoes. anything foreign is junk.  

Not every thing foreign just every thing from china.
I have seen test on the hurricane intake on a Pontiac engine and it made less power then the performer the rpm and the offy intakes and the only thing that was changed was the intakes.

I agree with one in particular that Pontiacman recommended. The Weiand Air Strike.  (I have one on my 350) At the very least a Weiand Stealth if you don't want the "Air Gap" style.
