Lq4 rebuild internal troubles

I just got my LQ4. Doing a swap in my 86 Monte Carlo SS. Will drive the car to work about 3-4 times a week to the track and to our weekend night cruisesand have some fun

. I want to take it on the power tour next year also. Shooting for 450-500 N/A with an MFI setup next year. Considering a decent build since I am putting money into the top end I might as well put a touch on the bottom end. I want to keep the stock crank.
A few questions:
What combination would be good?
Stock crank, stock rods, aftermarket pistons, arp rod bolts, standard bore or .030 (wouldn't mind a little more CI).
What aftermarket pistons are good?

I am having trouble finding threads on mild built bottom end LQ4's. Any response would be a great help. Thanks.

Check out K1 or Scat rods; both are pretty cheap $$ wise. I think K1 sells Weisco pistons and rings also. Gm High Tech did a similar build. It was around $7000 for the long block, but you might not need everything they built. AES' price looks pretty good.

No disrespect your work and products look great. This is something I have been wanting to take on and achieve my self for some time. So now that I have my block I am beginning to piece together my shortblock. I see you used the 6.125" 4340 forged rods. Are those H beam or I beam rods and can I use those rods with the LS motor and stock crank? I thought you could only use them with the standard SBC. THIS IS WHERE I AM CONFUSED. WHAT RODS AND PISTONS DO I NEED?CAN I USE?
