How much can a stock LQ4 take? I read through the stock bottom end vs boost list but didint really find what i wanted i plan on a stock lq4 with katech rod botls, arp head studs, and ls9 gaskets on 317s with hardend PRs. want to boost to 12.5 max on a mild SD tune using a t76 or 78. will that be to much for a otherwise stock Lq4 or not

I sure hope it will. I researched a lot for my build and it sounds like it should. I'm going the same route on a t76 with 15lbs or so,but I may do a cam in the spring. But my thoughts are if you keep the rpm down and enough fuel it should live

my 6.0l on 15-18psi and 16 timing lasted 4 years with rod bolts a tu1 cam with pushrods and 918 springs lol. Pump gas with meth. It still runs, just burns oil now 
limiter is at 6400 and man o man does it ever get used. I rape it religously.
