Just as an update I purchased the Autokraft oil pan.
My next purchases will be:
-TSP Camshaft Package w/ Dual Valve spring kit (Cam = 231/236 - .644/613 112LSA; PRC .650" dual springs; 7.400" chromoly pushrods)
-TSP Upgraded Rocker Arm Package (LS3 rockers with trunion upgrade)
-GM Replacement LS7 Lifters
The local tuner I talked to, that is well known and does a great job on everything, said I should easily achieve 500rwhp or better with this set up

I'm looking to build an LQ4 408 stroker to get around 550rwhp. I'll be getting my tax return soon so I'm hoping to pick up an LQ4 from the junk yard soon for about $800 but I wanted to get some questions answered before I start buying anything.
What's the best "bang for your buck" rotating assembly package/combination to help get to my goal of around 550rwhp?

The tuner said the vacuum was picking up as the rpm's went up so there's a good bit more to have up top if I swap intakes for a fast 92/92 setup. He said fix those and I'll make over 500 no problem
