Default will it hold?
stock bottom end lq9 with lq4 pistons. im planning on upgrading to the arp rod bolts, fresh bearings and rings. planning on running 10-12 psi with a 88mm turbo, 317 heads and studs of course. victor jr. with elbow. with a turbo 350. will it hold untill i can afford a forged rotating assembly and better heads? if necessary i can run a lower psi.

With a GOOD/SAFE tune you should fine with that much boost. Whats the compression with the lq4 pistons?

Why an LQ9 with LQ4 pistons? Why not just a LQ4 and change the rod bolts.

LQ9 rods are better anyhow, should be fine to 800fwhp with good fuel.
