Default Max power with Maggie? How to do it

I am looking for advise on how to get the most out of a magnuson on an 01 LS1 vette.

Engine is currently being pulled. Had Maggie @ 7 PSI w/ alky ...435 rwhp

I am looking at

Dart heads (205's)
Kooks 1 3/4 lt's w/ hiflow cats
Cam (please recommend) Steret car , a slightly rough idle is actually preferred)
Scat rods
JE pistons (please recommend a CR)

I know that there may be no real world results with the Darts, but does anyone have any recommendations for a good reliable combo, hopefully well into the 500 rwhp range?

Street use w/ under 7k redline.

TIA

Talk to Nineball(Tony) he's an administrator on here with a 69 camaro with a LS1 Magnuson pushing 500rwhp
I think at 500 a Mag is pretty much maxed out. You most likely need to be at about 8-10psi

yeah, I did some research, and it seems a little over 500 is about all it's worth. I have heard a rumor about a larger case for a magnuson that would be able to breath a little more.

On this project, I am stuck with the Maggie as is for the moment.

There is at least 1 vette (99) with a forged engine, 10.7 cr and maggie that is pushing mid 500's and running high 9's. Mid 600's with juice.

In that you can only get so much out of my Mag, what CR, cams can you recommend?
