Does the LSX block come with torque to yield bolts ala production blocks or high yield heat treated steel bolts like an ARP type?

are you talkin about all oem lsx engines? or the ACTUAL lsx aftermarket engine.

headbolts,rod bolts, main cap bolts, crank pulley bolt, and possibly cam gear bolts(not exactley sure) are all torque to yield.

The GMPP LSX Bowtie blocks come with OEM main bolts.

Thanks everyone for your replys. I needed to know if the 376 LSX crate motors came with TTY bolts or ARP type fasteners. Should have been more specific. I have no problem with the factory TTY bolts but I won't buy these for replacements. I plan to take off the heads and send them out for CNC work and then use ARP fasteners when it goes back together.

IMO - if you truly needed an LSX block, then you need ARP regardless of what it comes with. (LSX is only really needed for 1000+hp, and that requires ARP fasteners)
you will want ARP main studs (which require a main bearing hone), cam bolts & retainer bolts, head studs, rod bolts, etc.
