I have a steel 68 Cuda, 408 stroker edelbrock ported heads, 1 3/4 Hookers, 248-258 cam, 3500 stall 456 gears. I am running a RPM Air Gap and it does 7.0's in the 1/8th. Does anyone have any experience with the 340 victor manifold and do you think it would pick me up any in either the 1/8th or 1/4. I was originally worried about bottom end so I went with the dual plane air gap. Plus the magazine dyno articles say its the best, but that was mostly street and they didn't test a victor on a drag car.
