For those of you who don't know I bought an 07 Avalanche. Well none of you know because I don't have any of you on book of faces and haven't posted in a while. Long story short just had the trans rebuilt with high performance parts front to back. The shop warned me that the 5.3 isn't long for this world as the cold knock issue It's had since I bought it signifies the AFM lifters are donezo.
This brings me to you all. I've been shopping for a used 6.0 and the prices are right for an LY6 express van engine. The swap would be cheaper than a cam and lifters by about $1800 and I hate to have the same issue 50k from now after spending $4500 replacing what's there. So I'm wondering if an 08 LY6 6.0l would even work with the electronics or if the Express Van is wired differently. I understand I would need to have the ecm flashed with 6.0 tunes but it sounds like aside from that this is a plug and play direct swap which should be easy for any reputable shop.
