Need recommendations for rods and piston right on stock block ls1
I'm going to be boosting my trans am and I plan on running the stock crank and pistons but upgrading the rods piston rings an hardware. I will be running an f1-a procharger with a brute speed cam and 317 heads. What is the go to for rods and rings?

Here's what I'd do:
Wiseco Boost Piston and Ring package (best price from WS6Store) and the Callies Compstar H-Beam Rod (best price from BTR)

You need to hone it if you replace pistons. Also, you'll need to get everything balanced... even if you stick with stock pistons, new rods will have different weights than stock and will require a rebalance.
They don't make any drop in 3.898" pistons unless it's Hypereulectic. And I gave you the part number for the 4.03" bore pistons for the LQ4. Here is the 3.903" for the stock block:

Pistons are actually going to fail before rods in a low RPM boosted scenario. Most folks put new pistons in with stock rods for peace of mind. If you plan to really crank up the boost or spin it over 6500, get some new connecting rods.
Also, if you go with a boost piston, I'd look at 243s or As-Cast 220s. The 317s would put your compression too low.
If you just wanted to add boost to the stock shortblock, the 317s would suffice. And if you're not willing to tear it down and build it up with forged rods and pistons, I'd just keep it stock and limit the boost and RPM, keeping it below 600rwhp.

If you're going to go through all the tear down effort, then forged rods and pistons are the way to go. Those who prefer ultra-cheap (stock) have remarkable success by opening up the ring gaps (.026"-.030") and keeping the boost moderate with a conservative tune. Jacking it up to get that number...9s or 8s or whatever is where you will eventually find the weak link...more than likely the pistons.
