Factory LS6 cam vs......
Hello.
The info I have is that the basic specs on a factory LS6 flat tappet cam are 242 I/242 E at .50, .520/ .520 lift, and 114 lobe separation.
In comparing that to a hydraulic cam (not specifying manufacturer to avoid possible brand "prejudices") with 226 I/236 E at .50, 534 lift I/ .553 E lift, 112 lobe separation (I think), what would be the expected performance differences?
I understand some of the basics, but I'm not sure how the apparent decrease in duration but increase in lift might act relative to the factory specs in real world and what to expect as far as impact on performance might be. So if anyone has any "nuanced" thoughts (perhaps lacking some needed info I admit) I'd be interested. Thanks.

Don't forget to subtract lash when comparing the two.
IIRC the LS6 cam has around .024 lash so the net lift is about .496.
My guess is the hyd cam wouldn't rev as high but it would make more power in its range.
