I have a similair engine to that ,410 trick flows 11to 1 237/243 roller cam . used to make 392rwhp and all done by 5800. max power was @ 5500 and did a best of 11.4 @ 120 mph at the track. New trick flow set up now 425@5955 and pulls hard to 6400. Has lost a little of torque peak but holds a flat torque curve till at least 5600. Will be taking to the drags before christmas but waiting for my new Tachometer to arrive first and will report back.
