If I bore ...
If I bore ... How large can I go before my LS6 intake and 1 3/4" to 3" headers hold me back power wise? I am starting with an LS1 block and I still havent figured out if I want to stay at the 346 CI or go bigger. I want to go as big as possibly without worrying about my intake and headers holding me back!
Any ideas? Im looking to spend 6 grand or less.

There's no set size or power level when it hits a brick wall. I would just go as big as you want/can afford and not worry about the headers. You'll still make good power and you can always free up a little more with the bigger headers in the future.
an all bore 382 ( stock stroke, 4 inch bore ) have proven to make alot more power then a 383 stroker.. if resleeving the block ( probably more costly ) was your plan.. then I'd take the bore to at least 4.1.. you are doing it, mine as well. I think the CI will be in the 390's that way, and should be a real screamer too.

Judging by the posts I've read on the percentage of sleeved motors that have leaked, I'm gonna have to stay away from them. I'm not into pulling my motor to get it fixed even if the sleeve repair is gonna be warranteed. Just too much work. I agree though, bigger bore is the way to go if you can afford to do it. I also wouldn't shy away from more stroke though, especially if I didn't plan on putting a bunch of miles on it.
So, it sounds like the way to go would be to bore it out to 3.905(I assume no sleeves are needed) and then put a 4" crank it. Is the extra $1000 for a 4" crank worth it? What should I expect as an increase in HP from a stock forged 346 H/C to a forged 383 stroker?

so the best thing money wise would prolly be to just get the 4" crank, and keep the rest stock sized and just replace iwth forged stuff... ?

Well if you don't opt for the stroker crank then you basically have a 347, one whole whopping inch more displacement than what you started with. You could probably get a LS2 short block for what you'd pay building a 383.

Stock LS1 can only be bored .060 over.
I thought about re-sleeving - $150 a hole (roughly)
I currently have a 3.905 JE piston, balanced stock rods/crank and ARPs. Should easily handle 600HP... it has been proven.
Who makes your 237/242??? Very curious... I have a similar cam
