About how many horse power?

I have a stock bottom end 2004 5.3 truck motor. The heads have been ported ( intake and exhaust side) 5 angle valve job 650 lift springs and harden pushrods. Carbed intake and a fitech 600 power adder . The cam specs are adv.277/285
dur@ .50: 227/235. Lobe sep: 110.0
valve lift : .613/.620
my question is about how many horse power should I be seeing from this setup?

Yeah it’s set up for drag racing I’m eventually going to run nitrous that’s what I was told the cam was a nitrous cam and would lag out the hole if not sprayed

Makes sense. Assuming you're planning on shifting over 7k?

I have a similar sized cam in a 4.8. With a decent converter it will be fine. Mine makes power way up over 7k. I'd expect your 6800-7200 shift point to be about right.
