Cam and Fuel Pump for a 409 Buildup?

Cam and Fuel Pump for a 409 Buildup?
I'm building a 409 from a 6.0 iron block using a 4.0 lunati crank and a 4.030 bore. The heads are TEA stage 3 6.0 heads that will be flowing about 330cfm at .600 on the intake. And I'm using Diamond pistons and planning on a compression ratio of 10.8:1
What kind of camshaft should I be running with this sized engine. I want something with a bumpy idle. The more lope it has the better <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I'm also looking for more mid to high end power. But I still want plenty of power down low, but I think with the 409 that won't be a problem. This is going to be my daily driver so it still has to be driveable but I am willing to sacrifice some drivability to gain more lope and power.
I was wondering if the Cartek HSST cam would be in my ballpark? The specs are 238/246 .625" lift on a 108 lsa.
If that cam is too big, what should I be looking at? I also heard of a G5X-2 cam, at least I think thats what it was called, with a .612 lift if I recall. I cant find where to buy it though, but would that be better for this engine?
My second question is what fuel pump should I be running? I plan on using 38# Bosch fuel injectors. I was thinking of using the holley in tank fuel pump that flows 255 litres. Or would it be easier to just use an inline pump?
Thanks

Re: Cam and Fuel Pump for a 409 Buildup?
I ran the S1 (244/244//112) in my 422ci ironblock and it was pretty cool, I'd get it on a 114lsa for a daily driver. I had a 4.060 bore x 4.075 stroke and dynoed 475rwhp/505rwtq on slicks thru a 9".

No one else has any advice?
I had a TR 224 with 112 lsa in my motor before it blew. That cam didnt have enough lope for me, and was very driveable. I want something much more agressive compared to that on the 409 I'm building
