Can I get 400rwhp out of a cam and bolt on 6.0? I'm doing a LQ4 6.0 swap in a third gen this winter and 400rwhp is the goal. Can I do it with an LS1 intake, decent headers/exhaust, and a cam small enough for LS6 springs? I'd be okay with milling the heads to get the compression up.
Any cam and/or dyno results would be much appreciated.

In my opinion, you're going to need an LS6 intake, all boltons, and a cam like the TSP 224R. You may be able to do it with a little lesser cam, but not with a cam that's small enough for LS6 springs.
This is all purely out of my head with no dyno results in hand, but I just don't fathom it happening with that small of a cam. What heads are you using?

How much power is an LS6 intake worth over an LS1 at this power level?

LS6 manifold, ASA cam, LS6 springs, 1 7/8" headers and a 3" true dual exhaust

Auto or Manual? The extra 18ci doesnt make a huge power difference. If it were me I would never use a cam so small that LS6 springs are able to handle it. You dont need PRC duals but they are good springs. I would get a 228R from Texas Speed, order springs with the cam because you get an little $$ off for buying it together.
An LS6 intake makes a big difference on an LS1 with stock heads, IMO it shouldnt even be considered on a 6.0.

I did some checking on the ASA cam and it looks like it is pretty sensitive to backpressure. The exhaust on this car is a single 3" flowmaster so I'm not sure how well it will work. I'm going to build 1.75" headers and the y-pipe has a smooth transition.
Any other cam suggestions or dyno results?

I have not noticed any issues with the asa cam and backpressure. I run this cam and just went from duals to a y pipe and catback setup. If anything it runs better now. You can hit 400 with this cam or anyother small cam. It might be cheaper to just do springs and not worry about other boltons like the damn intake everyone praises. Get the springs and the cheater cam and thats your 400 right there.
