Default Northwind 4150 intake

Hi,

I want to go with a Northwind intake with seperated water crossover and wonder how it compares to the performer RPM on the street.
Car is a 66 GTO with 462cui, 236/242/144 HR cam, E-heads, Sniper EFI, 3.55 gears and a 4 speed Muncie. Should be around 500 or a little more hp.

Some say that the Sniper likes the single plane manifolds better. I think the torque will be a little less down low but I hope to gain some power higher in the rpm range. I also like the looks and the fact that the water cannot transfer the heat to the intake. I'd get it port matched, so that should be another benefit.

Maybe someday the heads will be ported and I'll step up to a little bigger cam.

What do you think? Will I at least get the same power or more out of the Northwind over the performer RPM?

Chris
