Nothing wrong with stock rockers, depending on lift. What camshaft are you using?
Id go with a Melling 10296 pump and have it ported by a reputable shop. Tony Mamo sells these.
Lifters depends on cam selection.
I run billet timing sets and Iwis chains.
You’ll likely get lots of opinions on this stuff. Just my .02...

I will add that the stock rockers are only capable of up to .660 lift. This was what I was told from a professional LS engine builder in the industry. If your planning on going solid roller you will need full adjustable roller rocker arms. T&D and JESEL makes pedestal mounted rocker arms for the LS7's but a shaft mount system would probably be your best bet.

Basically the 10296 pushes 13% more volume, which isn’t much with a 6 quart pan. The extra oil volume won’t hurt a thing in a street/strip car, and will actually help cool the bearings.
