are you hell bent on going fuel injected? if that’s your reason for going lsx i can understand. but carb’d will save you a shit ton of money and with a fat shot of n2o down the strip on some slicks will push you into the 10’s fairly easily with a slightly worked turbo 350 or 400 and some mild gears out back. it’d still be streetable as hell and you’d save enough money to get yourself some dot tires for the road.
