so its a completly different block??.. so its not like you can make an ls1 into it??

You can, but you have to sleeve the LS1 block.

Stock LQ9 = 364ci
LQ9 block with 4" stroke = 402ci
LQ9 block bored and stroked = 408ci

Stock LS2 = 364ci
LS2 block with 4" stroke = 402ci
Shouldn't bore the LS2 block.

what kinda power could range from that 408 combo?... and um... what's the weight diffrence between the Aluminum LS1 and the Iron LQ9?

[C&Cbird]

The heads you use depend on what kind of power you can make and I've read that the iron block is anywhere from 75-100 lbs heavier. Mr. Luos has a pretty mean 408 that makes around 520-530 or so RWHP. You can make more than that, but its not easy to do without nitrous or FI on a car that you drive much on the streets.

How easily do hey both go into Fbodies ? I know the LS2 has a few different sensor locations compared to the LS1.

Mr. Luos has a 402, 531rwhp.

Close enough, lol. They both go in fairly easily, just a wiring harness and something else for the LS2, the iron block needs nothing different.

Thanks for the info with almost 130k miles on the Camaro and turning over 6500 RPM at the track I think a stroker might be in my future sometime soon

what would be better/cheaper, getting the LQ9 block or just sleeving the ls1?

[C&Cbird]

Oh, the LQ9/6.0 block would be sooo much cheaper and better. You may not get quite as bit of a bore, but the extra bore isn't worth the price. The iron block can be found for 600 and below, the sleeved blocks are pretty pricey, I believe over 1500, maybe more, I'm not real sure.

will the Stock stuff... fit on the Block?... I mean... Water Pump, Power Steering, A/C... etc etc... heads maybe (even if you don't really use the stockers)... heck even the wiring harness and such....

ya im curious about that too.. can it just be like a direct swap?? kinda..

[C&Cbird]

On the 6.0 block, I think there is one bolt hole missing for one of the accessories, but it can be drilled and tapped fairly easily. Everything else fits just like it does on the regular ls1 block.

[Mr. Luos]

For the alternator.

I am using stock sensors and stock accessories.

Do you have the LQ9 block mr lous??

[Mr. Luos]

Yes.

[Rikki_SeVeN]

so after a CF hood (for us steel hood guys)...and a Lighter Racing K-Member... to even out the Weight of the Iron Block Vs. the Aluminum one... it would actually be a pretty damn good deal to go with the LQ9...
