Please bear with me, I just found this forum and have a question. Can anybody tell me what years the V8 engines will interchange? My brother just picked up a nice looking LS that needs an engine. Thanks for any info.
I'm pretty sure he told me it's a 2002. He found a 2004 wreck with a good engine but had heard they wouldn't swap.
2000-2002 - 1st gen.
2003-2006 - 2nd gen.
You have to stay in the same generation.
There may be something different for [late?] 02. It had a different part number when I needed one. I don't know what was different. I could ***guess*** it just means it was updated with the metal-bodied secondary timing chain tensioners, as both my original and the replacement engines had those instead of the failure-prone plastic bodies
The water to oil cooler is definitely a sport / non-sport difference, not a year change. Check out your local pick-n-pull if you doubt this.
There was an internal oil flow change in 02 to get more oil to the timing chains. The timing gears changed some too.
You need a different inner hollow bolt to convert from cooler to non-cooler. There's no need though. If you don't connect the coolant hoses to the cooler, nothing bad happens.
