LQ4 with LS3 intake and 823 heads

[KEWLKATDADY]

ok so I'm slowly getting my LS swap together.

6.0L LQ4 2005 DBW
823 heads
Aussie LS3 intake (I used this so the LQ4 MAP sensor plugs in)

Motor has 190K miles, going to have the bottom end gone through at the machine shop, stock bottom end re build.

823 heads will be P&P
Not sure on CAM...

I'm at point to where I need some advice.


I'm thinking aftermarket fuel rails, but which injectors?

What cam should be used. I'm wanting a STRONG truck hoping to get in the high 400's close to 500HP range naturally aspirated.

I want a truck to be able to driven comfortably, so I really don't want TOOO radical of a cam.


Next question is...
Flat top piston to raise the CR or factory replacement? Also, do I need to upgrade the connecting rods?

Thoughts?
