I searched but was not able to find anything on this topic, let me know if it has already been discussed.

I'm thinking about the LS7 cam (211/230), into an LS3. I like it that the idle is smooth and its easy on the valvetrain.

But, I see from some dyno graphs that the LS7 loses some low-end power in exchange for some modest gains up top.

Have people tried installing the LS7 cam with ICL down around 118 (Stock ICL is 122, so 118 = 4 degrees advanced) to move the powerband down some in an LS3 engine? Advancing it should in theory help out the low end power.

Thank you.

It does so from the extended exhaust duration, but it performs fine in a 427 due to the increased stroke and thus better torque down low.

In a smaller engine it will seem like it's peaky and yes you can gain some low end by advancing the cam a few degrees and increasing compression and thus torque.
