Im wondering what kind of gains can be had. Im thinking of a solid roller big *** cam so it will also help with driveability.
2800 isnt THAT bad considering what some of the other stuff costs if it will pick up a lot over a fast 90

I have a Harrop coming my way first week in April 
It's the version with 55mm throttels suitable for engine with large displacement (mine is a 427').
Their testing shows +40hp at the top-end compared to the FAST 90mm setup, from what I understand that is on a 350' so I'm hoping for more on my 427'. As you can see in the dynosheet the FAST is stronger at the low-end <3500rpm but the Harrop outperforms the FAST at higher rpm's.
I got some info(pdf format) from Harrop as well:

This setup is for SpeedDensity tuning only = No MAF !

$3,000 delivered to the USA. Should be good for 50 RWHP over an LS7 or 90mm intake. Aussies have been running them for a long time. They're friggin awesome and proven.

The prices are:
Hurricane Manifold as shown in the big image on the attached brochure (no airboxes) is A$3636 (~US$2727).
Installation kit inc airboxes, without the Holden Commodore tray/brackets, is $A650 (~US$490).
Freight (door to door) is A$700 (~US$525). I would recommend insurance, but I have not been able to confirm the cost yet.
Therefore, total kit price is A$4,986 (~US$3,740), plus Visa/MasterCard fee @ 2% = ~US$3,815
Please feel free to contact me if we can be of further assistance.
