I understand all of you guys are correct. But before we have the guy pulling his engine or throwing a rock through his engine builders window, lets see if it is an overheating problem and not an engine problem first. I would guess just because the engine is newer doesnt mean the remaining parts under the hood are also.
First off, be sure whether it is a cooling system/overheating issue or an engine issue.
Are you using a fan shroud?
Are you sure the the thermostat was installed correctly - not upside down? (Hey it happens)
What type of cooling fan and water pump are you running? If it is a stock fan, you have to be sure the fan clutch is kicking in and the fan is cooling the radiator.
Check the basics first - open the radiator cap and let it get up to temp - be sure the water pump is circulating the coolant - if it is basically full you will be able to tell if there is circulation at the top of the radiator.
If all of these things check out (which I have a feeling something wont) - Before I went into the motor, I would take the half an hour and the 10 bucks and install a 160 deg thermostat and see if that solves your problem. More than likely there is something causing the overheating that is just being missed. If you, or a knowledgeable person goes through the other options and come up with nothing, then pressure test the cooling system and see if there is an issue deeper within. Then it would be time to start getting upset with the person who built the engine. But there are alot of issues that could be the root cause that are alot simpler to check before tearing into the motor.
