Use the parts that look the best.

Thanks for your help. Much appreciated!

I found a 2007 4.3 out of a Sierra 1500.

It's a long block only, so I'll have to reuse the intake/fuel injection and front accessories of my 99.

Other than the above knock sensor issue, is there anything else I need to be aware of ?

I found a low milage (30k miles) 2006 4.3 long block. The only difference between this an my 99 4.3 was the style of knock sensor that was used.

My mechanic simply retapped the 2006's knock sensor boss to accept my 99 style knock sensor.

NO other issues to address!

So if you need an engine for your 99-00 S10 or Blazer, here's an alternative for you!
