Stan, you listed your base circle below previously in the thread so looking at the Butler base circle as noted above the Butler is a slightly smaller diameter, any idea using rough math if this will work with the Sealed Power lifters? Is there .023 wiggle room in the oil feed without having to chamfer the block? Again, I realize that actual measurements with my block & cam are necessary but trying to have as much information as possible before ordering the cam.

Base Circle 1.191
Lobe Lift .344
