I am going to be putting N2O on my forged and balanced 347ci. I was wondering how big a shot you all think i can run with it. I have picked out a ZEX LS1 kit the allows a 250 hp shot. Is that overkill. what do ya'll think. I know some people on here dont like ZEX but I think they are top notch and safer than Push Button Types. Any advice will be appreciated and i know I will need a tune for the nitrous to retard timing with that amount of a shot. Thanks Guys.
