Default LS3 blower cam specs

What would be a good LS3 blower cam? Its for a G8 Gxp so the car is a little heavy. Car has a maggie 2300 right now and is putting down 460/415 with 6psi and the guy is unhappy with the results. I'm trying to help him make some good upgrades and I think a cam and 8psi will do the trick.

What do you guys think about say a 215/228 .605/.615 on ll6 lsa or maybe the same thing on 224/232?

What would you suggest?

A local shop is suggesting a 228/232 .588/.595 on 114lsa....

Why so tight with square port heads? Does a blower change the separation that much?

Man I totally missed that this was for a LS3. End of the day and I was struggling lol.

That would change things around a good bit.

Before just throwing more performance parts at it, you should double check the car and tune. That is super low on power, there is something else wrong.

I agree the car is low on power, but it could be due to just too little boost.

The OP did reference going to 8psi so I would assume(that can hurt you sometimes) that it would be far less than that now.
