I have been using reverse pattern cams for years. Jon Kaase won the engine masters contest with a RP cam. He was very naughty: used very short conrods; used very tight LSA cam, 92 LSA.
Lsa on that cam was 98 installed at 92.
And in later engine masters comps that engine had a 256/264 @050 on a 108 and made a bunch more power, not solely for that reason though. Reverse pattern cams don’t work. That’s why no one uses them anymore.
