I need a little help.My buddies 97 Z is down for a couple of more months,and hes used to having a 10 sec. car to drive around.So with racing season here hes going nuts.So to ease the urge he ordered an NOS kit for his wife's 99 SS.The car is bone stock except for drag radials and a hooker muffler.8.40 eighth mile.So it should run pretty good on a 125 shot.We have very little exp. on LS1's so we need to know which plug and at what gap would be best?Any help would be greatly appreciated.Thanks

 

Here is some plug info..
