What is done on Alice ? Mid 70's are pretty respectable for a stocker.
From the research I've done 81 was an experimental year for the Shovelhead. They went low compression, and used longer valve guides for reasons no one seems to remember ... And the max lift for an 81 - without taking the engine apart - is only .430. So my cam choices for this stage of the project were extremely limited.
Best - and virtually only - choice I could find was the Andrews 1 grind torque cam at .427 lift. So I went with it, a complete S&S Hi4 single fire ignition kit, the S&S carb she already had, and a 2 into 1 exhaust (that was a bitch to find for a Shovelhead..).
The guy running the dyno was doing short pulls from 1-4k because of her age, and did not want to believe she was still a stock 80" looking at the numbers she was producing ... But she is.
I have a much more radical build planned for her, but I don't want to risk pulling the engine down without having a sufficient cash cushion to ensure she'll get put back together. She spent way too many years collecting dust in a bone yard to risk having her end up in a box. And most of the initial phase of the Alice project involved upgrading the chassis, suspension, brakes, transmission, and driveline to ensure she would be able to handle the planned power increase gracefully.
She is insanely fun to ride, and everyone that has ends up coming back grinning like an idiot.
