Bore a 6.0 to 6.2?

Is this an iron block? Cuz you won't be able to get an aluminum one to that bore unless you change the sleeves.
Even an iron block will need to be checked at 0.080 overbore to get you the 6.2 displacement.
And this does nothing to stroke, the stroke is whatever you set the rotating assembly to.

ALL LS2's were aluminum. The only iron 6.0's are truck engines like the LQ4 and LQ9 in the Gen III series. There are also Gen IV iron 6.0's but don't know the codes offhand.

Thompson motorsports offer a ls2 6.0 in iron and aluminium block, but under the aluminum its listed as new gen4 and under the iron block its listed as seasoned core 6.0, but in either case, get a 6.0 truck motor bore it out to be the same as ls3, throw ls3 heads and intake, shouldn't that make about the same power?

What are you putting this into? If it's a truck or drag machine, no problem with the iron block, but if it's something light that you want to handle thru curves, the iron block will mess up the handling to a degree. This is why iron block LS's never got put into Vettes or Camaros, or any other car, at the factory

Yes it would be in a truck, would that combo work and make roughly the same hp as a ls3? My current plan is to go with ls3 with trick flow heads, and fast lsxr intake and a stage 3 cam from brian tooley, but looks like it may be cheaper to get a 6.0 and bore it and run ls3 pistons, but if I remember right the ls3 has rectangular ports and the 6.0 has cathedral ports right?

What? An LS3 style build will make more than an LS2, it's bigger.
You need to do some reading and get a better understanding of what motors are what so that you ask the right questions. Your questions for the most part don't make sense.

Again, wrong place to ask all these questions this is someone else's thread that is trying to get questions answered, read up.
Yes you can make an iron LS3 if you take a 6.0 and bore it to 4.065 and put LS3 pistons in it. You can do an iron LS2 also. But they aren't an LS2 or an LS3 they are just built with the same stuff but have iron blocks. Yes ls3 is rectangular and 6.0 is cathedral.

On those motors that are 4" bore with LS3 style heads, do you know if they run standard size valves? I wasn't able to find what the minimum bore size is for standard valve LS3 heads. I know they make small bore LS3 heads that can be put on 3.9 ish bores.
