ls7 nitrous limits?
Hi folks,
How much nitrous can a stock ls7 shortblock take?
I keep hearing horror stories about thin cylinder walls and the "weak" titanium rods, but I havent seen anything to support this.
Has anybody successfully run a multi stage 200/300 shot?
thanks,
Steve

anyone have news to share on this?
I have a built LS7 engine with stock block, stock LS7 crank, Lunati Promod billet rods, forged Wiseco pistons and am wondering if this can safely take a 100-150hp wet shot? I have heard the stock sleeves could be the weak point..... It is in the finishing stages of assembly and would like to know safe nitrous limits with a stock block at least also.

Lance with the HPE z06.. his stock block survived for a while on a 150 shot.. i'm not sure if nitrous was behind the reason for his rebuld for a 427 that can take a 300shot or not.
I'd think 650-700rwhp should satify most of us.

What is the stock ring gap in the LS7?
Thanks, Perry
