LS1 engine with around 130.000 miles on it ?? What do u think ?

[ACII]

hy all

currently i do have an attractiv offer for a camaro LS1 engine with around 130.000 miles.

The engine comes from a accident car...the owner is telling that the engine is running fine without any probs.

According to my strict budget i dont want to rebuild the engine....
Later on i want to install a turbo kit...so i guess it would be a good time to rebuild the engine...

What do you think about the high mileage ??
Which tests can i do before buying ? The engine is already out of the car.

Together with the engine it comes also a 4l60e transmission..
What do u think about that ?

I know its a pretty tough question...i just would like to have some feedback of ur long time experiences

Thx a lot
Achim
