Sergf, My e-headed motor put out about the same HP as yours but with a Victor intake. When I replaced the Victor with a NorthWind, As you have, I lost 15 HP but gained about 12 lbs. torque in the mid range. On the street the NorthWind drives better but on the track the Victor will run about 1 1/2tenths faster. Both Manifoldes were port matched to the heads. I have a chassis dyno and trust me when I say that there are very few street cars that push 470 HP and higher. Nice motor. What are the cam specs?
