Gary,
Maybe the cam developer did a little research and found that cam and decided to use it as a basis for this cam. I think that the only suggestion given to the cam developer was to go with about a 112 LSA as Jim is concerned that under hard acceleration with a tight lobe center that there would be too much reversion and that fuel would end up going back up the velocity stacks as there is no common plenum in an independent runner system and therefore no place for the reversion to go. I know through discussions with Jim that fuel use at higher rpms is one of the factors that he uses in determining the jetting. It is quite possible that with a street engine and milder driving that I could have gotten away with the 106 LSA with only a little bit of fuel misting under heavier acceleration that I may not have really noticed; hard to say and I am by no means an expert.
Hope that all is well with you.
Jim
