Default 5.3 mods?

I'm throwing a 5.3 in my 300zx. And I've been wondering if it would be enough. OK I'm going with flat tops, ls6 cam, ls6 intake, 60lb injectors. I'm still not sure on the Trans. But I'm thinkin 4l60e with black box or th400 ether way a 32-3500 stall
goals are turbo 600rwhp by the end of the year and I already have efi live. Plus I need this car to run a 12.99 or better n/a. It will be under 2600 lbs.

I just wanted to make sure I'm on the right track with this build. and see if you guys could help me with a trans selection. Thank you for your input

Do you already have a turbo? Your goal is really easily as far as E.T goals go. Your car is really light..... you don't need 600 rwhp to run 12s......

I think he meant running 12.99 or faster without boost for now.

Even with 400 rwhp the car should blast 11s due to the weight..... which is not that hard to get.

Yes 12.99 or faster with out turbo is correct.
I'm just wanted to make sure I'm on the right track with this build. And I was wondering what you guys think I should do for a trans. I know 400 at the crank puts me in low 12s high 11s and at 600hp in the 9s

I was just wanting to know if my build was on the right track for my goals.
And I wanted input on what Trans would be best suited for my goals on a budget

Get 80 lbs injectors instead unless you already have the 60s. They are like $300 for Deka and will give you room to wiggle.

If you are looking for a built trans, I would think it would be cheaper and more reliable to go with the 400. With that said, I'm still rocking a 4L60E with a few upgrades and it has done well for me so far. Also remember, the 400 doesn't have an overdrive for street driving.
