what should i do for performance???
No, most of us do NOT like the LT4 hotcam kit.
It does provide a good gain over stock, but for the money you can do much better. The hotcam is built on LAZY lobes and old technology.
and as for the nitrous question. They like it just fine on the stock bottom end. RPM's will hurt the stock bottom end more than nitrous (rod bolts stretch). 150 shot done properly is fine. Mine's getting turned up to a 175 on pump gas soon, but I'm at high altitude.
