Best way to install new rod bolts???
I bought the KATECH rod bolts
In the instructions it says to torque bolts down to 30 ft/lbs then loosen. Do this procedure twice, then final torque rod bolts to 50 ft/lbs.
WTF isn't the rod bolts from the factory only torqued down 15ft/lbs with 65 degrees of twist?
That is according to the (how to build high performance chevy LS1/LS6 V-8's) book
Also do the old rod bolts just come out and install new ones?

One at a time ... You have to take the caps off and punch the old bolts out though. They have like a little collar in them. It's rather simple. Just follow the instructions with the new ones. THe stock ones are torque to yield, or stretch bolts. That's how they are torqued.

These instructions kinda suck they don't say anything about removing any collar. They have NO info on removing the old bolts. . If I take out the old caps then What? will I have to check clearance on rod bearings ? I a little confused. Has anyone installed this brand of rod bolt? don't know if ARP'S are different or not. Were is the collar? are they a pressed fit? I just don't want to screw anything up. Thanks for the help.

THe collars will come out with the old bolts. You just take the caps off, take extra care not to hit the bearing or get it dirty, and pop the old bolts out, the collars will come with them.
Get some assembly lub and put on the bearing halves before you put the cap back in place. If you have a lot of miles on it, you can replace the rod bearing while you are right there.

The engine has 23,000 on it but the bearings should be fine(I hope). Ok I now have a better picture of what needs to be done. So there won't be any clearance issues? The stock bolts only get 15 ft lbs of torque and these get 50 ft lbs.
