99 Wrangler LS1
99 Wrangler LS1 I swapped a 2000 LS1/4l60e into my 99 Wrangler. I've driven it for about 5 months and everything is good except for annoying knock on cold start up.
I've decided to pull the LS1 and put in a low mileage 5.3 for the winter and rebuild the LS1 over the winter.
I am going to use all the accessories off the LS1 including the intake and put them on the 5.3.
I know I need to drill and tap the block for the alternator. Anything else need to change?
Will the 4l60e bolt right up? Do I need a 2004 5.3 flex plate or the 2000 LS1 flex plate.
I'd like to think of it like swapping a long block.
Am I missing anything?
Thanks

If your using the 5.7 PCM you need to change eng size to 5.3 in your tune for fuel mapping and such. I would use a 5.3 PCM if you got one with the eng so you don't have to change the hundred different little airflow and such settings.
