[doaner70]

I was just wondering how many miles guys get out of these with the 5.3. mine has 250,000 miles on it and I beat it to death daily. I bought it with 30,000 on it and have done nothing but pull cars a with it for more then half the miles. and only thing I have ever done to it is put a tranny in it at about 190,000 and had to change the alternater last summer and thats it. other then oil and plugs never changed a sencer are anything and put a fuel pump in. o and it it a 2000 chevy 1500 z/71 ext cab.
