I have a 5.3 on a stand that is stamped A171 by the water pump. From what I have read this is January 17 2001 engine. Is this correct? I have checked and it is a 5.3 I have the chance to buy a 2005 Suburban that needs an engine. Can anyone tell me if my 5.3 will work? The local junk yard said the interchange number is different. Thanks for any help

 

It will work. The block anyway, some top end stuff on the suburban is different.

It should have a returnless fuel system I think and throttle body is drive by wire. But nothing that will matter too much.

 

Yes, The basic long block will work.

Some of the sensors changed as well as the throttle body, intake manifold, Exhaust manifolds and so on.

 

So will the long block work. I just have to swap all the bolt on stuff. Is the cam sensor in the same place? I thought I read it has the sensor up front like an ls2

 

Anywone?

 

Still in the same spot.
