YR, this is the OP's stated goal for this engine/cam on page 1 of this thread. I'd suspect this has a lot to do with the results... this project/design is not about peak HP.
FWIW..... The other thing about narrow LSA is that it is going to make your lower RPM engine operation less torquey. Yeah, I know, narrow LSA moves the torque peak down and/or extend the higher levels of the torque band down, and it does make the exhaust pull-through work better at 'lower' RPM's.. but 'lower' is all relative and is still up in what I would consider 'mid range' RPM's. Once you go low enough in RPM the exhaust pull through stops and the intake reversion goes up with a narrow LSA, and the torque is gonna drop off the table. That is a reason all of the catalog 'torque' cams have LSA's up on the 112-114 range. If you are running certain forms of engine operation, too narrow on LSA just hurts low RPM operation, regardless of carb or EFI. All depends on what you are doing with the engine.
