I steer Busa guys towards degreeing the stock cams in to where the factory intended them for the power gain which is about the same amount up top but the stock cams degreed to Suzuki spec will have a good bit more power in the middle range . Or if the customer could only afford one cam , maybe the little .330 lift WebCam exhaust to use with the OEM intake and here's why .
The Busa cam bucket has a .002 crown built into it for a purpose. This helps the lifter spin in the bore . The cam lobe should be concentric with the axis of the valve or center of the guide bore for this to happen and to prevent any potential for side load of the bucket in the bucket bore and any potential premature wear in these areas .
Center to center of the intake guides are 1.445 - Exhaust guides 1.350
This makes the intake cam lobe center , when used on the exhaust side over a millimeter off the guide bore center ..... half of .095 inch . Then there's the oiling galley and possible valve train harmonics coming into play .
I don't want to make anyone angry but I can't build them that way .
