N2O on a LT1

How large a shot of N2O could i realisticly get away with with out sacrificing engine longevity on a stock LT1 ? The only mod is a flowmaster cat-back. Also im new to nitrous, so which kit would give the best safe performance for say under $1200 ? Also, how much hp can the LT1's bottom end safely take before a rebuild with stronger forged parts would be needed ? I dont want to be replacing burned rings anytime soon on a engine with 13,000 miles. And roughly what does it cost to fill a 10lbs bottle ?

No such thing as a power adder that want cut down on longativity of a motor. Anyway do a search for the various questions you have and if you cant find something then ask. Not tryn to be an ars but most of questions are answered allready.

max i would say around 150 shot. you can eathier go with the nx wet kit or the nos dry kit. most people like the nx wet kit which is a good kit. them bottle will cost about $50 to fill it all depends on how much per pound it is in your area.

if your new to it, just do a 100 wet shot, u don't need retard or anything fancy with that on premium gas. I'd just run colder plugs with a tight gap or get a ignition and u can open it up alittle.
