Default How hard is it to swap an ls2 intp my 98ss?

my dads friend has a motor out of a 2006 silverado ss with an auto tranny an a harness for it. MY question is how hard is this to swap into my camaro, which is a 6 speed, so obviously ill need an ls2 flywheel, which will come when i get the ls7 clutch. what about accessories and fitmwn. motor mounts etc. also can i use my pacesetter lts? couldnt find much specifics on here yet. thanks guys

...whoa... sorry, my mistake. I have a 99ss and it could be an LQ9 motor, since LS2s never came in trucks. Thanks

there is a thread on this, on a side note the LQ9 is basically the same as a LS motor its just that its cast iron. generally alumium is better for more power as opposed to cast iron.

cast iron may last longer but doesn't withstand alot of power, I think the max is like probably 8-900 HP but people do go over obviously. alumium is better for building up power.

Who's the retard that says aluminum makes more power?!?!?
WHAT AN IDIOT!!!!!!!

hahahahaha.

The Cast Iron blocks are MUCH BETTER for making more power... they are stronger.
They're just heavier. You will not see more or less power at all depending on what block you use.
Someone kick this guy off the forum.

Really, that's why ford use's a alumium block for the Ford GT and are considering putting it in the 11" GT500. hmm.. I guess there making a mistake then I guess they don't know what makes power plus its lighter as well guess thats not true either.

you are an idiot

6061-T6 Aluminum -> 2,700
Cast iron -> 7,000 - 7,400
Magnesium alloys -> 1,760 - 1,830
Steel -> 7,850
Titanium -> 4,500

Ultimate stresses(1,000psi)
6061-T6 Aluminum -> 45
Cast iron -> 50 - 200
Magnesium alloys -> 20 - 50
Steel -> 80 - 180 (high-strength steel)
Titanium -> 130 - 170

Coefficients of thermal expansion(10^-6/*F)
Aluminum alloys -> 13
Cast iron -> 5.5 - 5.6
Magnesium alloys -> 14.5 - 16.0
Steel -> 8.0 (high-strength steel)
Titanium -> 4.5 - 6.0

I already knew that. but what I am saying Ford put an alumium block in the ford gt for a reason, some say its good up to 2000HP. its a romeo block thats why theres a difference in the cylinders walls of the romeo blocks as mentioned before.

obviously things are different for the LS series blocks.

then your argument makes no sense, you say go aluminum because you can make more power when that is not the case.

I know the 03/04 Cobra's use iron blocks, I am saying the Ford GT uses a 5.4L AL Block, and the GT500 use's the Cast Iron 5.4L with a wet sump as opposed to the GT using a dry sump.

I was saying that ford is considering using the AL Block for the up coming gt500, because it is lighter.

I was also saying that most LS Blocks are AL is as well as opposed to the LQ4 and LQ9 blocks. which are cast iron. I misread a post and I apologize no need to be hostile.

back on topic...
most everything from your ls1 will fit on the lq9 and it'll bolt right in. theyre both gen III motors. in fact, i can't even think of one thing that won't work since theyre the same block, just yours is aluminum and the lq9 is iron. the lq9 is also gonna hold boost a lot better if you go that route. its a tougher block and has lower compression stock for stock.
you might even get lucky and be able to get it to start, idle and drive on the stock ls1 tune. if not, call up one of the many mail order places. theyre an easy and affordable upgrade that yields good results.

LQ4 would be lower compression than the LQ9.that would be a better choice.

wow dude seriously, no I haven't been mislead my whole life don't know where that came from.

I am assuming when you speak of a cast iron motor, you speaking of either the LSx or LQ Blocks.

You can go either way with a turbo when it comes to compression, on the other hand going supercharged would result in needing a lower compression.

Personally Id go turbo with a LSx block.
