I use the RPM intake and like it a lot. My car is used for street and strip. The Victor 440 is a single plane intake were you can loose some torque on bottom end compared to the RPM intake which is a dual plane intake. To me your car would run better without a single plane intake because of you cam. If you would decide to go with a dual plane intake, make sure you gasket match it to the heads. The Victor intake is very good for top end. On a motor with a bigger cam and better heads, I would use the Victor 440, which I run on a 505 stroker motor in my other car
