LSx at the machine shop I just dropped off all of the parts for my LSx build. Here is a run down of what we're going to do.
Switch over to 1/2" head studs for the standard locations
Switch over to 3/8" head studs for the two additional locations
Bore to 4.165
Machine receiver groove
Line Hone Mains using standard ARP fasteners
Setup main support system
Restrict lifter galleys to .060 using threaded insert
Diamond pistons to be machined to remove ~5cc
Balance rotating assembly
- Diamond pistons
- Howards Rods
We've got a custom torque plate being made and should be here 4-5 days setup for the new block.

Are you machining piston oil squirters too?
Your LSX block is going to be thoroughly stiff with a main girlde

Sounds like a nice peice. I wouldn't think a girdle would be needed. I would consider a Jesel belt drive, lifter bushings and a dry sump setup. I have spun my LS2 setup to 8500 with no issues.
What heads are you planning to use?
Good luck

Sound's good I just worry if you get real crazy with the springs pressure will it hold up thats why I prefer the C5R setup.
