I got a 2005 envoy Denali it's got a 5.3 AFM was disabled from the factory due to exhaust issues I blew this engine I need to know what other engines I can put in here they used parts place as I can only put an 05 engine lh6 out of the same vehicle problem is there's only one in Canada and it's too much money is there any other LS engines I can put in here that'll match up I have my old engine so I can take parts off that if I need thanks

 

You should be able to use any year after 05, just none older.
Any Gen IV aluminum block 5.3 can be made to conform to the configuration required for your vehicle.

 

Well I don't know too much about motors like I said the dealership and all the used engine places that I can only use the one engine do you know which ones I could use are they going to be 24 times or 58 times I have don't know I need to know these things before I order one

 

Some Gen IV are 24x. Most are 58x. You need to know which yours is. No way for me to tell.

 

24X (2005-06), 58X (2007-09) this is what it says in the ls page mine's a 2005 so I guess mine's a 24 times

 

24x. Not 24 times. Has to do with the number of teeth on the reluctor on the crank.
And you are correct. The LH6 is the only Gen IV 5.3 that came with 24x reluctors in its early years. Others (LC9, later LH6, LH8, LH9) can be converted to 24x but it involves complete teardown.
What do you mean by "blew up"? It might be rebuildable.

 

For the OP - I've found that Car-Part.com has a pretty good search function, & after you've gotten the results of your search, you can re-order the search results if you need to. It might help you to find a better deal on a replacement if you decide to go that route.

Good luck!
