STillin CAMS on a 95 maxima,any thoughts?

Observations I've read is that it makes your idle less stable and a bit lumpy, but top end increases are awesome. Anything you can to add to flow, CAI and exhaust especially would only increase this car's top end even more.

At 120K miles, changing cams should be no biggie in terms of affecting the durability of the car. But, cam change is a bit of a heavy duty job, and since a cam change would involve removing the timing chain, may as well replace your timing chain tensioner and other parts in the timing cover etc, like maybe even water pump.

Hope this helps
