And one other thing FWIW.... I realize that a lot of the thinking about LSA and EFI comes from old experience of putting more radical cams with narrow LSA into a stock EFI system The manifold pressures goes way out of the 'normal' range for which the EFI programming was designed and the engine operation goes haywire. So those experiences color a lot of think and comments; I realize I'm guilty of that here to some extent.
