an AFR Head will get you there too.
Your power goals are easily obtainable and can be had pretty reliably too. Though supporting mods, sound building and tuning will help ensure max chance at longevity.

I know, I've ran trickflows and loved them so I'd stick with them. Probably would depend on who has the best black Friday sale between the two.
Do you guys sell rotating assembly?

yes sir we do. Can even balance them and set you up with prechecked rod bearing and wrist pin clearances. Unfortunately without the block we can’t set your main bearing clearance.

working on a new website. I had my first IT guy set it up and we couldn’t stop redirecting from less than appropriate websites. Just something that’s kind of been on the back burner.

Going to the dyno this Saturday but already thinking for the winter build.
Going back and forth on a built Ls3 vs a Built ls6. Im going to keep the Vortech TI V3 and pulley down to at least a 3.4.
Motors will be forged so Im keeping that out of the pricing.
Ls6 would just need some nice heads. That would be between 2 and 3k
Ls3 block adds 1100
Ls3 build would use stock ls3 heads. 1k to 1.5k with rockers(I know they can be had for less but keeping a realistic budget)
Ls3 would also need at least ls3 intake(200-300)
Ls3 intake needs ls2 throttle body (250)
Whatever else is needed to swap to a ls3.
Goal is 750 to 800rwhp.
Thoughts?

680whp from an LS6 with only cam?
Or only a cam and a blower?

Would I spend an extra $3,000+ to add 30ci on a C5? No. The goal/platform/use doesn't justify that expenditure. Those dollars could be better spent on a clutch/trans/tires replacement fund.. Or better yet use those dollars for track days, drag racing outings, etc

Don't dismiss the AFRs. Mikey just built me a kick *** motor with a set....go check out my thread.

AFRs are bad *** too. I've just personally ran the trickflows and had good success hence the bias. Honestly, if I can get a better deal on the afrs at the time of purchase, the bias goes out the window

i actually went from trickflows to afrs mainly because of time constraints but so far i have zero regrets.

Hello OP,
I recently went through this process and decided on the Ls6 in my 02z. My decisions were made after reading and becoming informed by Bret on this site. Some notes below:
Spend the extra money on having custom pistons done with large gap-less rings. The rings don't just maintain compression, but move heat away from the piston.
K1 rods are fine, so are the Callies
Stock Crank is just fine for your power goals
Just clean up the heads (no porting)...blueprint/shim springs/valve seal
Custom cam to meet your goals
If you have the money, move to e85 if you can get it in your area. Here is how you can make more power. For 3K you can improve your fuel system and make more power than if you did expensive heads.
Keep your blower setup...the ti can make 800rwhp.
As you can see you didn't do much except put some quality parts in your motor, made sure things are all tidy, and changed the fuel system.
I hope that helps. I have learned a lot going through the process myself.

I am over 550 rwhp thru an a4 forged LS6 Fast 102 lxr ls2 tb about 10lbs of boost. Thats about 650 at the motor.
An LS6 is no slouch, I am running cheap patriot stage III heads ported. They have the 2.08 larger intake valves.

Cheap way to gain some torq. I agree that the stock crank would also work just fine at that power level.
