how was the intake manifold designed? i noticed you used the upper part from the original manifold... did you calculate the runners length to be more effective at a certain rpm? is there info about the intake manifolds design? looks very nice.
there's a way to calculate the runners length using the way the air bounces between the intake manifold and the valves to make the air bounce just right so that it will be moving ointo the valve as the valve opens, giving more power... the problem is that it is only useful at certain rpms because as engine speed increases the bouncing speed remains the same and so it doesn't bounce in at the perfect time, unless you have a varying length intake runner.... that would be awesome.
anyhow so you can effectively calculate and use the length of the runners to make the engine stronger at certain points (such as around the big torque area, or horsepower areas.
