Rebuild high mileage LS1/T56 or just buy/install low mileage? I can't decide which I want to do when I do my swap. It would be a stock rebuild.
Rebuild high miles
Pros: "new" engine, excellent experience, get to by some new tools, lower initial cost
Cons: longer time frame, higher overall cost
Install low miles
Pros: easier, quicker
Cons: there's a chance of something being wrong with the engine when I get it even with compression numbers, etc
I have to knowledge and resources to do the rebuild. Eventually I will be doing a cam swap, so I could rebuild the top end then.

everywhere I've read said unless theres a problem with the bearings, dont change them (a bitch to do, and you have to shim the races in the front plate). I went ahead and still changed them. I figure if you are in there messing with it, you can pretty much figure out how to change the bearings as well.

I totally agree with building while it's apart, but I don't need/want that right now. Eventually, yeah. But I really want to run it stock for a while. In a 2600lb car, it's going to be fast even stock. That's a lot of the reason I want an LS1, I can have stock reliability with plenty of power. But where I do want to eventually upgrade, that's making me lean more towards buying a low mileage motor and not rebuild it right now.

is the motor actually dead? ev en if you get a low mileage block, you still don't know what your getting.
Do it right the first time? Why spend the cash on another motor? It'll cost about the same(if not more because it'll be hard to find a stock short block) or more. then down the road your going to spend more cash rebuilding that.
Save the cash and build the stock motor up..at stock power levels it'll last as long , if not longer than the normal life.

Well, I'm going against the popular vote here. I'm going to be buying a low mileage pullout and put that in. Down the road (a couple years I would assume) when I'm ready to make some serious power, I'll pull it back out and build it. That is, unless I find a really good deal on a high mileage motor/trans.
