What else?
the logical next step for your current motor would be heads. there are better choices than the Dart 225s, obviously depending on budget.
not sure why you think heads would "blow up your engine"? as long as its in good running condition now. obviously any increase in power has the potential to trash the engine, but that could happen with cam only.
1000hp and street friendly....hah...good luck.
only way to get anywhere close to that would be big cubes and forced induction.
check the dyno section...seems like i recently saw a 800rwhp LSx build up on there.

I'd say that you've pretty much squeezed your engine dry w/o upping the cubes. Assuming you are being honest about the numbers, i wouldn't level too much more power on that thing. The LS1 is a strong block but it does have a breaking point and you might be flirting w/ it.
I wouldn't judge people like that. Unless you know this guy personally, on what grounds can you speak accurately about his intelligence? I know it seems pretty far fetched, but i've seen people put down some nasty numbers that i didn't think were very propable...
considering some of the best built heads/cam/stock cube cars on the planet are still making well under 500# of torque....i'm pretty impressed that you're beating them by 250# of torque...cam only.
even at the crank...a 500hp engine will only make 450# of toque if you're lucky.
i am not sure i've seen a single LSx motor...stock cubes...make more torque than hp.
so if you're going by what T1blackout said....you got taken for a ride!!! BAD!!!
i suggest you do some research.
oh...and i'll bet your 408 won't even make 750# of torque...FI or not.
Either way you're not gunna blow your engine up by adding a set of heads.
GL with whatever you decide to do in the end.
I really dont mean to Rain on your parade bro, but I dont think anybody has seen a 200 horsepower increase with just heads on an LS. Even if that was on the flywheel. If that were the case, then it would be true that those heads would actually give you 170RWHP when you bolt them on. AFR's, which are pretty much one of the best heads out there for the LS engines, give you around fifty-something rearwheel horsepower. And Thats their best heads. Oh, and those heads "DO" outflow the Darts.
Bottomline, do the research yourself, dont rely on other people.
And to your question, Yes definately go bigger engine. You will always get more power through a bigger Motor!!!

So what is your budget? Cause youre gonna need a 408, nice heads, a big *** turbo, new tranny, new rear end, upgraded fuel system, and tons of miscellaneous other crap to reach your 1000hp. and most people once they reach 450-500hp realize that is plenty for a street car.
as a wise man once said, everyone wants 1000hp with a 400hp budget.
and you dont have 750lbs tq by the way. youre prolly putting down 380/365 to the wheels.

Lets not pick on him. if he has that, then we have to take his word for it. But if you don't have that, let us know, but don't bullshit bullshiters, dont come up with made up numbers. Cheers
