Speed Inc. 231/237 Cam
#21
Unless I'm mistaken, Speed Inc uses Comp Cams to grind their cams... The TSP 231/237 is a Lunati cam, and is on less aggressive lobes than what Comp Cams uses. That's why the Comp will most likely put out better numbers... the TSP cam would be easier on the valvetrain.
Nice numbers!
