OP, call Texas Speed and talk to them about what you want to accomplish and they will point you in the right direction. There are a bunch of good experienced guys over there

No ****......11.1 408 with boost, that's awesome. Do yall think my 10:1 compression with 24* of advance on 93 octane is on the weak side?

$800 seems about the average price of a lq4 100-200k. Never know what condition the motor is in until it comes apart.
I believe the lq4 heads have a 71-2cc, so flat top pistons with stock gaskets and NO milling will put you right at 10.1:1 compression. But if you got some 243/799 heads which have a 64cc with flat tops you will be at 11:1 compression.
Shoot for 11:1 with a N/A motor
Here is a great tool for calculating compression

Yea I seeing around 1000-1200 for low-end forged up to 2500 for high-end.
Here what I would do, call texas speed and find out which pistons and rods you will need for your power goals. Remember the stock GM rods and pistons internals are strong/reliable to 500+rw, so you don't need to get the best forged parts. Call other people and start another thread about brands and models.
Once you figure out the exact parts you want then type the model numbering or just piston name/specs in google shopping and it will list almost every web site online that sells that model.
