Lightbulb Pro-Street LS3 Power?

I am saving/planning to build an "Old School" Pro-Street car.

I was thinking E-85 Gen 2 SBC or 502 based BBC but the more I hear about the LS engines the more I want to know.

One of my best ideas is a 1970's Ford Maverick with a carb'd LS3 engine(400-430 HP), carb'd intake with a Holley 800 Double Pumper,TH-350 tranny, Mopar Super Stock leafs or Cal-Tracs Monoleafs/Dana 60 rear 4.57-5.13 rear gear(either an Excited or Air Locker),Either Mini-Tubbed for 30X13.5X15 or Tubbed for 31X16.5X15 M/T ET Streets, 6-8 point rollcage, 'glass hood& trunk,aluminum door panels with manual crank windows, Front& Back windows replaced with Lexan.

Could I run Low 11's- High 10's N/A with this combo?

Are there N2O cams for LS engines?

The Maverick, being lighter in weigh than some others i am sure, should be light enough to run its *** of with 450+ RWHP from a cam and carb setup. high 10s with the combo hitting right if the cars weight is around 3000 or so. Especially with those deep gears and a good trans and stall combo.

I dont think you'll have any trouble running low 11's, or even into the tens with a decent 6.0L.
my cam only 6.0L ran 11.39 @ 120 in my 3425lb 67 camaro 5 spd

Question

With a 28X13.5X15 tire a 5.13 rear gear is a 4.76 when teamed with the TH-350's 1st gear of 2.52 and a 3600-4200 stall convertor it should leave hard.

Would a TH700-4R be a better choice than a TH-350(it has a steaper 3.06 1st gear)?

This my idea is Save/Plan/Buy only once.

Can LS engines like your 6.0 be bought whole from a Salvage operation?

If an LS engines runs carb'd does the stock distributor still work?

That is a great time with a 364 cube engine.

The 700R would be better for street use and would leave a bit harder with the deeper 1st gear, the engines are everywhere in salvage yards for 800-1200$ complete, there is no distributor anywhere, here is how mine looks carbed and you can also see the MSD ignition controller:

Like ZONE, I got my 6.0L LY6 from a salvage yard for $1500(canadian$). it had 27K miles on it. All I did was stick a cam and valve springs in it.
My opinion on the trans is this: if you plan on alot of highway miles, then the 700r may be the right choice because of the OD, but for drag strip use, the th350, or a th400 is the way to go. If BIG POWER(supercharger/turbo/N2O) is planned on, then a powerglide is the right choice.
edit: no distribtor needed, just an MSD 6012 for 58x ignition system. 6010 for 24x

Yea, if there is more than naturally aspirated power other than a 150 shot in mine, a TH350/400/PG is the way to go. I hate the power glide though, 2 gears? Man, i hate having 3 if i go auto so a PG will never be an option for me.
