I'm betting man, to say if we were to re-do the dyno testing again with a Matt Sheare's ported LT500 engine and pipe combo we might have seen some different graphs, and this is the point I want to  make about each builder has there own recipe they use to build an engine (Pipe, Porting, Head, Carb,Clutch), change one thing and the end results will differ, the graph testing we did was to use a average 90s type of porting with pipes, and used Dales HPR Dunner Ported quad, the results were not for bashing, only to see the graphs from each pipe effect on each engine, the results are what they are.
