gude aint too bad on the NA stuff, their cams are pretty nice, but SUPER aggresive.
I made 166whp with my FC headpackage with crower stage 2 cams, which idled like stock with my setup.
FS makes great power too, and great topend, their guys are making 150-160whp on their packages, and still run a stock TB, mafs and intake manifold, those 3 added it should easily be a 160-175whp package...
Off all the gude cars ive heard, they have a really really aggresive idle, make good power, great topend, not much torque.
The FC package seems to make most torque only because of the cams they use, both other companies, FS and gude use more aggresive cams, but then again, FC makes pretty much what you want so you can have any cams, up to stage 4 race crowers, which in their race car keeps making power to 9000rpm
