Default Highest N/A HP with a FAST Intake?

Who’s made the highest N/A HP with a FAST Intake?
I have seen a few over 550HP
All those in the mid 500hp or greater, tell us about your set-up;
Port work done on the Fast, CI, TB, Heads, Headers size, Cam spec, est.

ECS and Cartek have done 580-600rwhp with a FAST 90 on their 447s. 260 duration cam, usually low 11s compression, Kooks 1-7/8", and heavily ported LS6s.

I'd think with the 265s from ET and a similar cam and more compression, 600+rwhp with a FAST would be possible with a 447. Then, add a custom ET intake to it and pick up 50-100HP.

That is awesome!
What type of porting has been done to the intake?
Can you show a graph of the dyno run?
That is about 40 to 50HP higher then I have heard of.
Great job.

MTI Racing's development C5 Z06 has a 434ci with 605whp/575whp. I don't know the exact specs but it does have a ported FAST with AFR heads.

CARTEK did a hydrolic roller 427 that hit 600HP a couple of tears ago in a Electron Blue ZO6. It belonged to Brent who recently sold it.
