Which rods and pistons?
Which rods and pistons? Here is the setup i finally decide to go with. I just need to know what type of pistons and rods i should go with. 2000 LS1 block 3.905 bore. What type of pistons and rods would you all recomend. I'm getting my crank polished. I'm running a G5X3 cam and want to run as much comp. as possible while still having a safe PTV clearance. I'm getting my 2000 heads ported and polished. How much should i get them milled and what type of piston should I run to achieve about 11.5 to 12 comp ratio. I'm also going to be spraying 200 shot of nitrous. TIA

im running custom diamond pistons w/ 6.6 domes, eagle 6.125 H-Beams, 5.7's millled .020, and cometic .045 gasket and my SCR comes out to 12.02
you'll need domes or a shitload of milling to get 12.0 CR. better off to start w/ a 5.3 casting as you'll start with a smaller chamber and wont have to mill as much.

Yep You would definatley be better off staring off with a 5.3 head.
You could then run a Flat top piston with a .041" gasket and not have to mill much to be in the 12:1 range.
You probably wont have to worry abot P to V clearance if you are getting aftermarket pistons as they will have valve reliefs. Good Idea to throw some weak springs on and check it tho.
