Looking for a good cam for street driven Lt1. I don't want to go lower than 113 on LSA. Close to stock idle would be good, but not a necessity.

I have a 97 TA LT1 M6, stock cubes (350ci)

Tea Stage 2 Ported LT1 Heads flowing like so:
.200 142 111
.300 200 165
.400 242 204
.500 270 229
.600 267 243

Plan to use one of the following: (T76GTS, T76 Q trim, or equivalent) on a TTI setup (yeah I know it sux, but that's what's going in for now), Delta Waste Gate, 42lbs injectors. Spearco FMIC.
Starting at 8lbs of boost, will move to 13lbs but not in near future.
Looking for good throttle responce from 2800ish to 6000ish RPMs, don't plan to rev higher than 6000 for now.
I do have N2O I want to use with this, no more than 150 shot. Probably just a 50 shot to cool intake temps. might possibly do a meth injec syst.
Wanting high 400's hp with this, maybe into 500's without N2O.

Which cams will get me this?

Are you sure those numbers are right? The exhaust looks amazing compared to other LT1 heads - so much so that I think it's a typo or someone's lying to you.

Check out their web site here: http://www.totalengineairflow.com/pr.../gmhead/gmlt1/
advertised numbers are right there come pretty darn close to the results above. although the exhaust side flows more like their stage 3 port job. would this make a difference in what cam to run? I imagine that the greater exhaust flow would reap some bennefits somewhere...

They must be using some tricks like a pipe on the exhaust. TEA isnt the only company out there that knos how to port LT1 heads I would guess the true number is more along the lines of 200-210cfm on the exhaust at .600"

yeah, I think that's it, but along the lines of being on topic....???

That has alot to do with picking your cam It helps to know the true flow numbers...and those arent the true numbers compared to how everyone displays flow numbers. Either way, I responded on cz28.com, just thought I would jump in on the flow number inconsistencies.

should i go get them ported before I pick a cam out then? I didn't think that would make this big of an impact on choosing a street cam.

Just to give you an example, I put in your flow numbers compared to LE stage 2 numbers and sine your exhaust is so high, it pushed he peak power up 500rpm. I was using an online engine sim. to spec a cam and I got the few I mentioned on cz28.com to peak at 5500rpm. I then put in your flow numbers and it jumped to 6000rpm peak power.

I am no expert, but I hav been playing around wit am specs for the last few weeks and how their powerbands correspond with different variables.

What I would do is bring the heads (which are already ported since you listed flow numbers) to an independent shop and have one cylinder flow tested (meaing one intake and exhaust valve).
