Hey guys, I'm building a 2000 5.3. My laid out plan is 862 heads ported and polished, TR220 cam, LT headers. Also wanting to do an intake and tb, but haven't decided on which I'm going to use. And of course a tune before someone asks, thinking about doing the tune myself or getting a nelson performance tune. Ok, so my question is what numbers should I expect with this setup. I posted in here cause I'm sure a few guys have run this setup or something close to it, and I wanted to see what I should expect.

Thanks in advance,

Brandon
