1.7 Yella Terra rollers
Comp pushrods
U/D pulley
Double row timing chain
ADM intake / MAF

PCM4Less fan harness
High flow oil pump
3" custom magnaflow mandrel exhaust
Stock heads
Stock manifolds
Stock springs (have patriot dual golds going on custom heads; some day)
____________________________________________________

This helped me out when I did mine. People had qouted me anywhere from 650 to 800 bucks... NO WAY! I bought two primary tools to do this, the rest I had. If you are mechanically inclined, YOU CAN DO IT.
------------------------------------------------------------
1. Remove the rockers and pushrods.
2. Spin the old cam over several times. This gets the lifters in the up position.
3. Insert the two 5/16" rods.
4. Now you can remove the old cam and insert the new cam.
------------------------------------------------------------
Tools-

Thunder Racing: JPR LS1 Cam Installation Tool $84.99

Tims Cylinder Air Fill as well as the Spring Tool - Shipped $50

Wish I did my own.. Shop that did mine removed the heads to do the cam swap.. Taking extra precuations they told me.. I'm still a little bitter about that whole experience. You want something done right, do it yourself. I think Napolean was the first one to say that.

Did you need to evac your AC system? It looks like yes, but I was hoping they would push out of the way, like on the CTS-v's.

i evaced my a/c system and removed everything that i could so i could have more room made it alot easier im sure.i feel alot better about doing it myself especially since no extra bolts (atleast the ones that should have been left over)and she started up right away it actually went back together well,i would do it again if i had to.oh and you have to take out the radiator/condenser to get the cam out so yes evac the system.

Ditto... Purged the a/c, that was the only real thing that sucked. Took it to the dealer and they were not happy to re-fill, but they did.
Yes, mine started up as well, just used the V2 to adjust the idle rpm's.

wow.How long did that take?
Im wanting to say about 12 hours total.

Gotta have beer breaks, picture time, and more beer along with the war stories from the neighbors.

Started saturday morning, finished up on sunday. Overall, it was not all that bad, fairly easy if your mechanicly inclined.

That is more of a Cliff Notes version than a How-To. If anything, you just scared people from attempting to do it on their own.

LSx cam swaps are probably the easiest swaps ever. GM really engineered the motors to make it as painless as possible. Honestly, the hardest part had to be changing the springs. The actual swap is easy.

I did my own on my 00 SS Camaro. I dropped a lifter since it was a high mileage motor and when I spun the cam they all locked up but when I went to slide the cam in one fell. I didn't use the rods that help hold the lifters. I used magnets and my buddy wasn't watching and let one fall. Needless to say I had to pull a head, drop the oil pan and the windage tray. WHat was a 8-10 hour job turned into a 24 hour job. But on a low mileage motor I wouldn't be scared to do it again. In fact I will be doing my own cam install when I get ready to do it.

The LS2's come with the heavy duty chain already. All I did on mine was pull the timing gear off. Didn't remove the oil pump at all. Reused the water pump gaskets as well. I swapped heads so I pulled the lifters out. This was the first lsx head/cam swap for me or brother-in-law...started Sat morning and running by 5PM with about a 2.5 break in between.

See Resources.... If thats not enough info, then your right, DO NOT ATTEMPT TO DO IT YOURSELF!

My point was to show you (with some pics and RESOURCES) what it will look like when ripped apart...

How do you like the Vinci #56 grind, I was looking at either that or the xxx from Vinci since both have the 115lsa and I was eventually wanting to go with a blower. Is it pretty streetable? power gains?

Wow!....that is quite a jump with cam, intake, and tb. These LS2s really seem to respond well to cams. Those are some nice number with the s/c too, I wish ATI would hurry up with the kit for us, guess they are having trouble making it fit. Thanks for the link....and keep us posted on the results if you dont mind!
