346LS1 500rwhp NA
Why don't you just go with a custom cam. I recommend Comp, but that's just a personal opinion. There's no such a thing as a perfect 'shelf' cam. It's ALWAYS best to have one ground to your head specs.

theres no static calculation, just gotta get out there and run. to many variables to could of, would of, should of.

.Another good example is Lee's (FEAR THE LS1) setup. He made 481 RWHP and 545 RWTQ and at a 3,470lb raceweight went 10.36 @ 131. Keep in mind he made that power through a TH400, 4" Steel Driveshaft, 12-Bolt, and 29" Slicks. At a 3,280lb raceweight he went a 10.11 @ 132 MPH. A 200lb drop in raceweight gained him .2, which is huge when you're in a class as close as Factory Stock.
The point here is that there is more to going fast than making good dyno numbers.

Didn't he say he was running a 4400 stall allready? Hence he has an auto. I might be thinking wrong here, but 500 rwhp is hard enough to hit on an m6, but an auto? I can't see that happening. Not on a 346 anyways, but who knows.

All it takes is $$$ and a willingness to have a 'track-only' car.

Sure you can fly-cut the pistons and use modified cylinder heads, but that's never what this cam was designed for. It just happens to work.
KCB, or should I say, Mr. Crapbox, is making sense here...It's just like having a custom cam ground for the flow numbers/specs of a set of modded heads, only this was made to take full advantange of the factory heads' flow capabilities. For obvious reasons, it still makes great power with modified heads-it's a beafy cam, just not as great as some other grinds as it wasn't directed towards modified heads.

As far as machine works goes im not fimilar with the LS1 but i assume u need the same things as a normal SBC done. What kinda power whould i need to run a mid to low 10seconds with assuming i have tracting.
with a 4400 stall, good luck getting 500rwhp

We made 503/455 with Lou's G5X3 pkg. With a FAST90, Lou's headers, and all the bolt ons.
Now, the big thing is a good set of heads (AS, GTP, AFR225's, etc..), and a cam matched to those heads. I think you can go past 500 with a hyd roller, but you can't just look at more duration as the criteria for design.
I have some ideas in this area for some max effort stuff.
