Whos the man or place to talk to for a 10 second NA LT1 6 speed I am thinking about a heads an cam package for my Z. I think 450rwhp should do the trick. Any suggestions?

You have a couple choices.
1. Combination Motorsports(Best cam guys anywhere)
2. Jordan Musser(Great Advice and head porting is great)
3. Lliod Elliot(probably spelled wrong but have heard praise of his head +cam package).
4.Advanced induction(Great praise on their head porting)

There are quite a few shops out there that can help you on your quest. Getting 10s on a 6 speed isn't all about the total hp though. Get ready to put alot of time/money into suspension. I've been working with thunder racing to help me "tune" my car to make it. I know they have a stock bottome end car that made 450 rwhp with lt1 castings also. May want to give them a call if your shopping around.

It still feels fine and can chirp them all but it wont hold up to slicks.

Verdad Gallardo get ready to replace that rear end and your gonna need alot of gear. 1.4x 60's are just about required to get a 6 speed in the 10s with small cubes. I'm swaping my setup to lt4s and later a converted intake. I'm shooting for mid 10s now on a 355. You can make it just don't be dissapointed in the initial results. From what I've been told and seen...once you get past 11.5s with a manual it gets a good bit harder to pick up et.
Thanks, best mph is 125.8...but I spun on that pass and only went 10.97. My 60' was .1 slower than on my 10.93 run and I was at about 1000 DA higher. I think my current setup with my current heads would be good for a low 10.8/high 10.7 run and mid 127 mph but the air is going away untill next year so we will never know. With my new setup I hope to be pushing 130 mph NA...still on a 355.

I have a Moser 12 bolt w/ 33 spline axles, HD eaton posi, etc. This should be good enough....? or no?... Damn 127 that is awesome. What are you shifting at. Do you mind if I ask whats in your bottom end. Haha that doesnt sound right.
I shift at 6900 and have stock crank, ross pistons, eagle h-beam rods. Im running a 31 spline moser 9" and run a 4.71 gear. Your gonna need 4.56s to try and get it to run to its potential with a small cube motor. This is all with a 28" et drag. If you stay on a 26" tire 4.30s will do better for ya...but you won't get the 60' where you will need it. I run the spec stage 3 clutch. Its done well for me. I've also heard good things about rams agressive line of clutches.

what rpm can my stock bottom end handle. Do i need the hydra rev kit even with a good valvetrain package? 4.56/ 28's is an option. How much modification is needed to fit the 28's?
I wouldn't go past 6700 on a stock bottom end...and thats pushing it I feel. Yes, you will need a rev kit and the right cam even to go that high. A little finder clearancing was all that was needed behind the rear tire on my car.
