Difference between 2001 Camaro LS1 and Corvette LS6
I have a 2001 LS1 that was pulled from my Z28.
I was lucky enough to receive the LS6 block in my car. I know that the block and heads are the same, and that the heads are different. What are the internal differences in these motors? I would like to fully upgrade this engine to atleast a stock LS6. What will I need to do this, besides the heads? Looking to get it ready to swap into a '57 Corvette.
Perfect! That makes it easy! All I need is a set of complete heads, and I have a custom ground cam, that I never got into LS1. I'm thinking I should probably get a new set of push rods though, I case any of mine are bent, and maybe a fresh set of bearings. Then all I have to do is throw the cam in, the heads on and reassemble, and I'm good to go right?

With an aftermarket cam it's not probably, it's definitely you should be getting a new set. Not only do you need the stiffer version, but might even need a different length.
Oh and springs also, not sure if you accounted for those when you said complete heads.

Ok, that's what I thought. I also have the Manley springs that were used on the same car that the cam was in.

I'm not sure of the cam specs. The guy I got it from had it custom ground from Comp Cams. I may be able to get the specs from him, if not, when the car is dyno tuned it shouldn't be an issue if I don't have the specs, right?
Just FYI. The pistons are different, LS6 pistons are made of a stronger aluminum and shaped slghtly different than LS1 pistons. F-bodies which received the LS6 block did not receive these LS6 specific pistons, nor any other LS6 specific parts. By no means am I trying to convince anyone it's worth swapping pistons. The PCV systems are also different. The LS6 PCV system (specifically the '04 and later PCV systems) is worth swapping though, easy and inexpensive to do.
I knew that the Fbodies basically only received the block and intake from the LS6, which is the reason for my post. If there isn't much difference, there is no real need to change them. The cam I have will provide a horsepower advantage over the stock LS6 anyway. What all is involve in changing out the PCV system? I'm not going to run nitrous or a power adder to this engine anytime soon, and if I decide to later, I will change out everything to forged internals. The car I intend to put it in is far too valuable to get too crazy with considering my limited budget.
2004 LS1s (GTOs basically) were the only such engines to get the LS6 intake manifold. The pre-2003 LS1s in fbodies got the regular ol' LS1 intake manifold.

I have held both sets of pistons in my hands they are the same. In 2001 there was as slight ring problem on some engines which was changed in 2002 along with the pistons getting an external coating on them but this happened to all ls motors otherwise they are the same pistons.

The aluminum alloy is different between the LS1 and LS6 pistons. Standard LS1 pistons were made by Mahle using an aluminum/silicon alloy called M124. The LS6 piston was made from an alloy called M142, which had a higher nickel and copper content to strengthen the piston. They basically look identical to the naked eye.

Part numbers are exactly the same. http://www.trademotion.com/parts/200...&siteid=214858

Yep, I had the oil consumption issue due to the #2 compression rings.

Are they that much more durable than the LS1 pistons? Do they result in the same compression ratios?
How much more durable, not a clue. But a good aftermarket forged piston is an upgrade to either one. Both pistons result in basically identical compression ratios.
Not saying you're wrong but I've NEVER heard that and they even share the same part number then and now. Like I said gm changed the piston design in 01 then again in 02 in all ls motors
I've read about it and seen it mentioned quite a few times. Do a search about it and you'll find it too, if you're interested. I don't think it's very well known, probably because it's never been a big deal.
I know that forged pistons are far superior to anything used stock, but it doesn' t seem to me that there is enough difference between them, to go through the trouble of swapping them. Unless the specs on the crank or crankshafts are different, I will leave the internals alone save for maybe a fresh set of bearings, the cam, and pushrods. Either way this will be a good upgrade to the engine that originally came in the car it' s going into.
It was said earlier that the Vette Ls6 had lightweight valves , just to clarify in 2001 the LS6 did have 243 heads but did not get the hallow stem intake and sodium filled exhaust valves til 2002. That and the cam change and couple other things is why it went from 385 hp to 405 hp in 2002.
There were differences between the Fbody LS6 intake and the vette LS6 intake . There are many that thought that the F body LS6 intake flowed better , I don't believe it to be true and have not found any proof of it .

Well that's news to me. An LS6 intake is an LS6 intake...
Idk where people get stuff like that lol. The ls6 intake is an ls6 intake. The part numbers are the same for aan fbody, cts, gto, or vette there are a few part numbers for the ls6 intake and all were put on all the different types of cars.

I have seen both part numbers on multiple vehicles.
