single plane intake manifold on a SBC
At what point do you gain by putting on a single plane intake on a SBC.. This motor will be WOT 5500 rpm and it is used above 4000 rpm most of the time. Low end performance is not a issue...
Any input?

if the intake you have now is a restriction at high rpm, and you don't care about losing a little torque at low end, than try it. you have emi's on the exhaust already so i bet a single plane will help.

You're not nuts, we're just slow. 
A single plane will boost top end with a loss at low end while a dual plane will boost low and mid range, not as good at top end.
Running at 4K to 5K is in the single plane range.
I think a single plane is good from 2500 on up.
Does that answer yopur question?

Thanks guys. 
I think I'l run a single plane and if i don't like it, I'll put a dual plane on it .. simple whos cares how fast you get going..... all that matters is who gets there first
Jr- I don't know what my heads will be yet.. So i don't know which intake bolt pattern i will need. Once i find out I will let you know bro.. thanks

Your light rig will like the single plane manifold. Find a Holley Strip Dominator and run it with a 1" spacer. My dads 355 loves it and it still has plenty down low. You can find those manifolds for sale at nearly every swap meet in America for around $75 to $100 bucks.
