Yes... this is a pain that I know now.I can sympathize with you there as I am in new Zealand and face the same challenges getting parts that I can't return if they are incorrect.

When looking on efi, torque/power curves the intake is made for trucking up to 3000rpm.Stock intake chokes at 4500 RPM, so you're on the right path by tossing it. You might consider a 454HO cam from GM.

What year is your rig and what are your local tuning options?
Yes! Nice that I want to know more.I used efi multiport intake to open up rpm band. Idle is a bit harder to tune with short runner intake, but low rpm torque did not really drop off much if any. Stock air box can hold a large aftermarket filter and can use 4" intake pipe to the throttle body. Much cooler charge and is worth using unless replacing with a larger box.

It is a tall deck 8.0l version that was put together with forged rods/pistons and stock forged crank. e38/t42 combination ecu/tcu from 2008 gm truck is used. I had to use 2008 or older e38/t42 ecu/tcu because 2008 was last year for a manual shift transfer case option with 4l60e that I needed for 4x4 to work correctly and segment swap to 4l80e controls.Yes! Nice that I want to know more.
This is my napkin concept in real!
It is quite tall Holley, I see aluminium heads.
You have standard 454 or this is 3500 forged version?
What EFI you have ?
For ProFlow - you will need a hood rise for sure !?It is a tall deck 8.0l version that was put together with forged rods/pistons and stock forged crank. e38/t42 combination ecu/tcu from 2008 gm truck is used.

But 411 ecu with dbw support would work as well depending on what timing reluctor is used. EFI connections is about the only place that sells 24x reluctor, while 58x set up kit is still available new gm. Throttle body is slightly higher than with a stock intake. Other option that I am working on testing is edelbrock pro flo intake, but don't have it set up and running yet.
Big blocks get expensive. And stock set up is really not bad for what it is.For ProFlow - you will need a hood rise for sure !?
Do you know what you are now getting from current setup ?
Or can you help me out what will be my result of me setupe
ECU 0411 + intake+ throttle + LT headers + EFI rails+ "standard" bosch injectors + roker arms 1.7 (in total i think in parts it will be ~2000$ - that I know.)
Waht could be the result of sepnding my $$$ ?
Rough pricing - Intake with fue rails - $900, Elbow adapter - $120, Throttle body - $300, Injectors - $500, Fuel lines, fpr and related fittings - $500, Intake piping and maf parts - $350, ECU and needed wiring to then rework - $300, Pedal with module for dbw - $200, 24x conversion parts - $400, individual coil pack set up - $350 range. Then for cam/pushrods in $600 range.
Heads could use a bit of porting at that point or changed and that can run to $3k by it self
Hah.... 3.73 is what I have and 33" are on my way.Big blocks get expensive. And stock set up is really not bad for what it is.
My set up is built for boost, but in NA form does outperform a stock l29. Running a stock 454 suburban(with 4.10 gears) against my version(with 3.73 gears), I still get slightly over 3 seconds faster 0-60mph times. My gearing is really not friendly with 33" tires down low, but set up for 80mph cruising between destinations.
On a stock 454, just going for intake change might not be that much of a difference. Might be more cost effective finding a whipple set up for around $3k or so.
