Iron 5.7 Issues
Has anyone had any issues with boring out a 5.3 to a 5.7? I ask because I just had this done and now it runs much hotter than it did before.(203-225) Specs are 5.3 bored .125 to 3.905 with 317's. (The rest is in my sig) I know there are several people who have done this but I haven't heard of any issues...

Yep, they sonic tested it and everything looked good for the operation.
It's not boiling over but if the ambient temps are 95+ and I'm in stop and go traffic, temps will climb pretty quick up to 230-240.

The engine was assembled by the shop doing the machine work and it was running hot. Then another shop removed the heads to replace some bad lifters and put new head gaskets on and it still ran hot. Not sure if both shops would have put the gasket on backwards....but who knows....
We replaced the temp sensor before installing the new motor back in the truck since it broke in the transportation process. It also has a brand new water pump. I'm lost.....
