questions about ls1 swap

[TXsilverado]

my buddy is about to do a LQ9 swap on his camaro and is guna get rid of his 5.7 LS1. he said $450 takes it. it runs great, but im a bit worried about the milage on it.

the motor:
85,000 mile LS1
a very large cam that i could sell(been with this cam for about 3000-5000 miles)
918's and hardened pushrods
has had a couple bottles of nitrous through it on the stock tune(before cam)
it will have the lq9 intake, and oil pan on it.

why dosent anyone do LS1 swaps anymore, is the LQ9 THAT much better? if i decided to do this swap what hurdles would i have? would all of my front accessories just bolt right up to the ls1? and the pacesetter headers. what about them? i also have an underdrive pulley on my truck. will that swap over or am i out a few bills.

i think i can answer all of my own questions on this but im just making 100% sure. all accessories will swap except for UD pulley right? i can reuse my computer but will it run on my 5.3 tune good enough to get me to SA? or should i just ride this motor out and find a lq9 when the time comes. too many questions lol.

oh, and the motor is currently in a standard car. will it mount up to my automatic 4l60e without any issues?

I say go for it. Mine had 114,000 on it when I bought it and it ran fine until I blew it. Everything will interchange except the UD pulley, headers included. Lots of guys are still doing the LS1 conversions. Nitrous just finished his. You get a 100 lb savings with the LS1. The only bad thing about them is they don't rebore better than .008 or so. For the cost of machine work you can buy an entirely new block if needed. The 6.0 is only 18 cubic inches bigger than the LS1. Your transmission will work with it also, just be sure you pull the pilot bushing out of the crankshaft before trying to stab the convertor. Not too sure they will work together.

There is a bushing pressed into the center of the crankshaft used for the standard transmission. The torque converter fits into that spot on the automatic.

gotcha anyone else have any info about the swap for me?

what was the 2001 LS1 rated at HP and torque wise? how much should i gain in the 1/4 over my truck with the same exact mods minus the underdrive pulley (suppose i put factory cam back into motor)

[motoxlifer]

I think the &#39;01 was rated at like 320 at the crank but not with that intake. They came out with the LS6 intakes in &#39;01 & &#39;02. These engines usually put those kinda #&#39;s to the rear wheels. Man 85,000 miles ain&#39;t shit for that motor. What are the specs of that cam? I might be interested. Oh yeah what casting # is on the heads?

[RedHeartbeat]

That year model should have the 241 head casting. They conservatively rated the HP in the LS1 engines so poeple could afford insurance. Most LS1 engines put out 400 hp with nothing more than headers installed.

From what I&#39;ve seen there isn&#39;t anything too big for a truck&#33;

Damn, does that mean I have to take out my .610 lift 234 duration cam out?
