I read the whole thing and am still not sure. The guy talks a lot about being a 1 piece roller block then shows a 2 piece crank. Too large a cam IMHO. I will agree that Speed-Pro has a better piston than KB though.
Another thing, why go to all the trouble of a roller block and not put in a roller cam? He offers it as an option
