Ls Nitrous

I need to know what a safe shot of nitrous to use on stock ls internals, and modified fuel system . Also i have a chip that alows me to shift up to 8500. what would be the safest to shift at.

Well for your stock LS I'd say a 50-shot would be safe, maybe 75 not sure. But before you go with nitrous, consider this: It's been my experience that you get more respect for your car without nitrous, especially an LS all motor. I mean anyone can strap on a few bottles and call it a day. But when you win races, do you want people to say, "Man that LS is sick as hell"..."Yeah he really spanked you man". Or would u rather hear, "Man that LS is sick as hell"..."Yeah...with nitrous". Think about that for a bit.

Very true, so do you think i should victor x intake manifold, throttle body and spacer?

Well u can do any all-motor setup you want. But, you wont really need the Victor X unless you're turbocharging, it produces way more power with turbos. You can pull off a great all motor LS without it.
