Accesory drive interchange question
 

Will the acessory drive from a Gen II pre 2003 5.3 work on a gen III L33 engine? Power steering, alternator, etc.? I got the engine cheap without the acessory drive, and I don;t want to spend as much on the drve as I did the engine. LOL

Any good (read cheap) ideas?

I tried searching but I must not be using the right terms.

First off, a Gen II is the old school EFI LT1. For truck engines (4.8, 5.3, 6.0) Gen III is anything from 99-07

Secondly, all the accessories are modular and interchangable. There are some mods that must be done sometimes to correctly utilize different accessories. For example, 4th gen F-body accessories require a bolt hole that does not exist on an iron block truck engine. The boss is there, you just have to drill and tap it. There are some variations, but for the most part, unless you really know what you're doing, you'll need to keep the water pump matched with the rest of the accessories, to keep the ofset from the block the same, and the pulleys all on the same plane.

You can get crazy with it if you want though...I've swapped a truck pulley to a camaro pump and run it with truck accessories in the past.

Go to the junkyard and find the accessories off of a junk LS truck. I can get them in my local junkyard for $50-100

For some reason I was thinking the Gen III engines didn't start until 2002. Yeah, there are loads of 99-2002 trucks all over my nearest pick n pull. They never seem to have anything newer.

As long as the accessories from a 99 - 2007 truck will work, I'm good.

Thanks!
