Will this cam work with factory LS6 11 to 1 pistons without any notching requirements?

Never actually tried it but probably not. .100 more lift & tighter lobe seperation which both bring the valves closer to the piston.
You are going from about .500 lift & 114 seperation as I recall to about .600 lift & 110 seperation.
In any event, you would need to check it ut I would think you will need to notch the pistons.
Maybe someone here has tried it??

BorderT,

No......
Notching would be required with the 11:1 pistons. The biggest cam that will fit in without notching is a 292/302F12, still 255/264 at .050, only .586/.586 gross valve lift, and 112 LSA. I think it will fit in with a 108 ICL, but , as always, you need to check.
The 292/302 is in my 272/282 family, excellent street life, decent power, etc....
