Does this prove David Vizard's 128 lsa formula ?
I pulled my Larry Shepard book and my 2005 PAW catalog books to do some LSA (Centerline) comparisons based upon this discussion thread. It seems that the trend is to use a 110-112 LSA for street or mild competition and a 108-106 for maximum or modified competition.
As was previously mentioned, this is old knowledge that is still valid today for these type of engines.
