I'd like to see what that 346 would do with 11.5 or less compression.
Now let's see that dyno graph.........

How many 346-350 cube engines do you know of that make 520 rwhp NA on pump gas? This is quite an accomplishment, and a new record for LS1 development. If making 500+ rwhp was so easy, everyone would be doing it now. You already know what guys are making with 11.5 cr and factory intakes, about 425-450 rwhp.
There is always a sacrifice involved if you want to make alot of power. I'm sure we may never see a 500+ rwhp 346ci daily-drivable, pump gas running LS1, that will last 100,000 miles. Lets be realistic here.

Ran 9.89@143.5 on a spinning 1.50 60' even jetting down 50hp.
Here is a run down on the setup:
-FMS Race ported LS6 heads,2.055"\1.60" custom Manley valves
-FMS nitrous spec solid roller cam -? ( not that little 233 cam )
-T&D rockers w\Comp 9990 coated 1.55" springs
-Diamond custom nitrous pistons 13.0 CR
-Eagle H-beam rods
-FMS custom sheetmetal w\dual 58mm T\B
-FMS 1 3\4"-1 7\8" stepped headers w\bullits
-Autolite AR472 nitrous plugs on C16 gas(not N\A friendly)
-STOCK water pump still
-12 bolt w\4.30 gears
-22lb steel driveshaft
-steel flywheel w\RAM 910 clutch
-Stock SS wheels w\275-40 DR's
It still drives good on the street,just a little more choppy at idle. Once I get the trans out and pro-shifited,will be making some more passes in Jan.

Did you see that 427 build up More Peformance did? I think they hit almost 800HP. Yes not the same cubes, but they had a high CR and were using high octane gas to get those numbers.
Put 93-94 octane gas in there with the same tuning, then lets see how much power it makes, probably 470 RWHP...
I am far from an expert, but seriously, having a high CR and high octane fuel, you will get higher HP numbers regardless....

Like he said , for street use,93 octane. I know of lots of guy's who add race gas at the track or for street raceing with just over 11 to 1 . With 104 octane he probably would make more but not nos freindly.
(Put 93-94 octane gas in there with the same tuning, then lets see how much power it makes, probably 470 RWHP...)
WHich is still awsome, put 116 fuel in the other high hp cars and see what they do, drop off 20 hp or so.

Not yet, very soon... with the exception of me playing the other night I have been doing nothing but trying to get our new shop ready. Finally got finished today, moving in tomorrow.
Might be able to make some NOS pulls this weekend.
