So my mechanic has put the 2014 engine in my 07 yukon and he is saying it wont crank up and its not compatible. We are not using the donor harness or computer since i didnt buy that. Is there any reason why it wouldnt crank up?

No i don't have the body harness for the 2014. I may consider adding vvt to the existing harness in the future. I was concerned about seeing a check engine light being on if it's disconnected Sent from my SM-N975U using Tapatalk

Thanks for the info. I was thinking about bypassing the vvt. Or do you recommend the vvt? If i bypass it, would i have a check engine light on? Sent from my SM-N975U using Tapatalk

Yes it does. Thanks for the fast reply. But what about the front? I'm seeing the cams are different. This is a picture of both engines Sent from my SM-N975U using Tapatalk

I have an 07 yukon with 5.3 flex fuel. I bought a 5.3 engine off a 2014 cop tahoe. Do you think the 2014 tahoe engine will be compatible with my 07 yukon?

I wonder if he's ok. He has not been active Sent from my SM-N975U using Tapatalk
