camshaft duration and lift ???
You just have to pick good specs for your cam, because you might loose power.
I assumed you been have them retard your timing by 3 degrees as opposed to calling someone a retard? You'll have to let them tinker with it to see what setting makes the most power.
Give these guys a call. They may or may not have a grind for your engine. They maybe able to make something for you. There regrinds are 93.50 per cam.
