10.0 na?
What would it take to run consistent 10.0 NA? Can it be done with a LS1 with good H/C/I and the right gear, converter, etc.? I have a set of 243 heads that I was going to have AI do and add a Tick cam and FAST intake but feel that may only put us in the mid-10s. If it can't be done with a stock shortblock what would be the easiest way to do it without a power adder?

You would need a spot on LS1 setup to be a 10.00
Consistent 10.0's means you really need 9.8's to compensate for DA etc etc.
A simple stroker will get the job with gears and 4500+ stall

Less weight and more hp...and traction.
I ran a 3400lb 67 camaro with a 700hp bbc and a 150 shot running 1.4 short times. It would consistently run 10.00 @ 135-136mph, with an occasional 9.8 @ 138+mph on a cool night and well prepped track with 60ft times dropping to 1.38...and a suspension setup to transfer the weight as well as 12" MT full slicks.
How you get a NA LS1 to do that even in a 3000lb car will take hella horsepower and the right suspension and tires...and I don't see it happening with a NA LS1, no matter how radical you build it.

I don't see it happening consistently with a 346. Hell, I have a 427 in a dedicated 3000lb drag car, and I'm not consistently at 10.0. Under the right conditions, I've run 9.8x, but to get a consistent 60' required to run that number is tough with an IRS. I'm working on it. And eventually, I'll get there. My mph is 137, so, I'm making the power, just sucking at the 60'.

So a nice H/C/I 346 (stock shortblock) is only going to be good for mid-10s in the right conditions? Looking at the ET list it's even going to take a lot of work to just get there.
What about a LS7 properly prepped?

I'd see a max effort 346 having a stout forged short block, the best heads you can find, prob hand ported TFS, a Holley ram intake, and a solid roller setup. Big stall, low gears, tall slick.
As Cap said, will be tough on the hook end unless you always run on a perfectly prepped track.
A 427 would make the job easier for sure.

When we went to Super Chevy in Ennis a few weeks ago there was a CLEAN white Firehawk out of the DFW area with a LS7 that easily went 10.0x. In fact, he had a bunch of timing pulled out to slow it down since he didn't have a cage. I do know that it had a Rossler 3-speed auto and a 12-bolt but don't know the specs on the LS7 other than it was NA and extremely, extremely clean. Don't even know where you would purchase such an engine.

Kurt Urban performance.

ERL
LME
Just to name a few.
LME is down by you. (I realize Texas is pretty big, but they're down that way somewhere)
Was the guy with the firehawk named Kevin? I believe I beat him in the finals at the NMCA race in Atlanta last month. That's a really nice car.

If I had a auto with 4500+ stall attached to my old 416 it would have gone mid to low 9's. That was a totally street worthy motor too. For some reason the 416 motors fly even though just a few more cubes than the 408 and 402's. For around $9K you will be smiling

a 700 hp 427 is a relatively basic build.
I was running 10.05 - 10.08 all day Saturday with a 1.5xx 60' If I could figure out my launch/suspension issues, I wouldn't have lost round 2 of the 10.0h index...

Easiest way IMO is a well thought out and tested heads/cam/I with spray.
Mid 10's n/a
10.0's with right amount of nitrous, no problem.
If you ars set on n/a only then I have a motor that will do it but not sure what's most important for you.

Do you plan on alot of street driving?

Mid 10s H/C/I was our original plan. After some research I thought about AI 243s, Tick SNS Stage III, and a FAST 102. We currently have a Nitrous Outlet wet kit and NANO system. We've dyno tested the kit and on a 100 shot it made 502 to the wheels (130 over NA) but have yet to sort it out at the track.
Before I had some heads done, as well as ordered a cam, I just wanted to make sure there wasn't a better way to get to our goal.

Very little street driving; if any at all. We trailer it to the track.

I'm thinking a well setup H/C car should make 425-450+ depending on dyno,etc.
Say 435 n/a + 130 N20 = 565whp
That should give the car potential for consistent 10.0's. Of course you need to iron out track details but the formula makes sense.
Years ago we had an auto in our camp that ran 10.5x's- 10.8x's n/a and 10.0's with nitrous. This car was relatively heavy and in street trim with basically no weight removal.
It ran a best of 9.7x on a good track/air day.
I also believe my n/a motor would easily run consistent 9.9x's setup properly and tuned well in an auto like yours and would be relatively bullet proof.

I'll wind up selling my setup at some point for 1/2 the price it will cost to build.
