402ci LS1?
402ci LS1? Hi, I'm new to the boards. I originally owned a 3.8L 1998 Camaro...would've had an LS1, but insurance was high enough on the V6. That, plus a low-paying job don't help much.
Anyway, I had an idea. I'll be graduating from school in a year or so, and I'll be looking into an '01 or '02 LS1 Camaro. I've been doing some research into certain modifications. My plan for the engine is to get the GMPP LS6 conversion kit, as well as a stroker kit. The stroker kit would bring displacement up to 382ci. I was screwing around with possible bore/stroke combinations. the stock 3.900" bore of the LS1 combined with the 4.000" stroke of the kit gives the 382ci. I thought to myself, "What if I increase the bore to 4.000"?" The result would be 402ci...and the car would be effectively an SS396.
My question is, do i have to make any serious modifications to the block to bore it out .100"? a friend of mine told me it would have to be re-sleeved. I've only heard this term before, and I don't quite know what re-sleeving entails. anyone wanna help me out on this?

The LS1 cannot be safely bored out that much, or effectively at all. People running larger cubes either use a differant block or re-sleeve the LS1. Re-sleeving is basically adding new cylanders, jackets, and such.
If you're re-sleeving, there's little reason not to go even bigger than 4.0". But if you just want a 402, you can buy an LS2 block, which already has a 4.0" bore. LS6 heads will bolt right on to that, but there are better heads and certainly better cams to be had.
Do some searches and keep reading. Good luck!

what heads should be used with the LQ9 block? LS6 or LQ9?
my aim for this project is over 500 HP on the motor alone, and still uses pump gas. I know the LS6 heads have higher compression, so i'm a little wary of using them.

I'm not sure what type of compression the LS6 heads would make with the LQ9 block. If it's the standard 10.75:1 ratio (it's somwhere around there, right?) then that's fine, I'll just use those.
I want the engine to run on pump gas. here in New Jersey, we have 93 octane (most other states i've seen have 91 as their highest.) As long as it'll run on at least 91 octane, that's fine.

Looks they are everything they were supposed to be and you know what they are gonna flow gauranteed.
I was thinking pretty much the same thing over the last year and waited for the AFR's to come out, now I'm waiting for the LS7 heads to come out

I think obviosly you will need a block with a bore big enough for the 2.2" valve so the new 7.0L block will be a good thing to pick up at the same time as will the new LS7 intake

Here's some nice pics someone posted in the LS2-LS7 section.
