need info on assembling LS1

i need some info on assembling complete LS1 short block. I didnt take the lower end apart so i have no idea how to put it back together with all the torque specs... any info or diagrams would be greatly appreciated, or any weblinks to that info also... all i got is a bag of bolts and what not...

Thanks in advance

ive done H/C on these motors 3 times, but never did anything with the shortblock... i took the heads off, and sent it to the machine shop to get honed and cleaned up for the forged internals, but i didnt have a pulley puller to take the balancer off so i sent the whole short block, and they took it apart... so now my rotating assembly is at another shop getting balanced, and this coming week im gonna attempt assemble it on my own.. but have no idea any of the torque specs for any of the bolts other than the ARP rod bolts ...

Buy a Haynes manual, GM Service Manual or have John and Raven come over to help.

All the main cap bolts are torque to yield except for the outside ones I believe so you will need to buy new ones (I posted the part numbers for the bolts in one of the above stickies). If you wanna go with arp main studs you will have to get the main caps align honed. The caps are a snug fit so you will sort of have to force them down in there. As for the torque specs and sequences I don't have them handy but as mentioned before there are books available I ended up buying one as I couldn't find everything I was looking for online.

Edit: The part numbers for the main cap bolts are 12560272 and 12560373.
