All I know is what I learn from talking to the engineers and racers who run this stuff. Blower Drive Service says that they have consistently had better results on gasoline with a 110 LSA, so that's the info I pass on to others who ask. They say that you may want to open up the LSA for alcohol, but tighten up to 110 on gasoline.

You're reading this out of the context it is offered for. They are refering to a 671-871 blower motor.
And refered to seeking a specific effect whe using more agreesive blower boost.

While a split cam that does have a 110LSA is not a deal killer on this motor. The 112 and 114LSA cams have proven to work very very well specificly in this type of motor with the 144 blower.
