bearing question i guess this is the right place for these questions. i have the opurtunity to pick up a 6.0 motor for cheap, but it has about 200k miles on it. i plan on dropping it in a fox body, and carbing it.
1.) how much mileage are these motors getting before bearings start going? 2.)would it be ok to throw a ls6 cam in it or bigger and run it at the track?
3.)or should i rering it and put crank and rod bearings in it?
4.) would it be ok if i just threw in some stock replacment bearings?
i'm trying to do this car on a small budget.

Well, it would be nice to do a rebuild, but there are many ls1s here with many miles and no problems. Since you are on a budget, I would do the simplest thing - take off the heads and look at the bore, and take off the oil pan and look at the main and rod bearings. If everthing is okay, just reassemble and do nothing.
Just pay attention to cam bushing wear, which some people have complained about on their inspections.

As far as cam goes.......What heads? What intake? and many other things to consider before i would pick one. Hope this helps

i would say go for it. Since you are carbed you will have alot easier time tuning. Where you meaning stock LS1 heads, or 6.0 heads. Good luck, she should really move.........although i dont think i could ever bring myself to put a GM engine in my Fox body 89
