I had our KG7 ground on a 110 lobe sep. I think carbs would have been better, or if fuel economy didn't matter in our application. Makes me think about L98s in the late 80's, early 90's...the cams that places like Arizona Speed and Marine or Lingenfelter were all ground on 114 or MAYBE 112 lobe sep, so there was onlt so much total duration you could put in them. Couple that with poor head flow and a restrictive intake (sound familiar?) and you were only going to get so many rpm, and with that only so much hp.
