I plan on putting the following cam in a boneyard 5.9 Magnum engine, for my street dart. 279 duration, 225/225/106 @ .050 with .480 lift. There are different runner sizes available from what I here, with the Edelbrock airgap being the biggest, and the Pro products ( chinese knockoff) being the smallest. I want lots of torque in the 2500 to 4000 area because the converter will be a fairly tight street unit,(2400?) with the car being primarily a street car.Has anyone done any back to back comparisons on these, dyno or drag strip tests, and what were the conditions like stall and traction?
