Nothing wrong with those numbers. Even better if you've got the 87-92 forged pistons! Check your #3 main bearing and a few rod bearings to make sure there not excessively worn and go from there.Ok guys, I could not get the motor over 154 degree's F. I am not sure why due to not being the orig owner so I will find out soon if it even has a thermostat in it. The car had some minor mods from back in the 90's. It had a flowmaster catback, msd ign coil, air horns and a flex lite radiator fan that was clutchless, permantly mounted to pully. I removed the setup and installed a new ford clutch fan and clutch.

I'm with you here, I'm so lost. My stock 5.0 has 170k miles and I still bounce that thing off the rev limiter all day.Why are you tearing apart a 39k mile engine?
I feel your pain... NO such thing as a cheap build... I would rather use parts and a machine shop that I pick though, rather than buy a " rebuild" off of ebay..I did the same thing with a '99 Explorer motor that was supposed to be a cheap build. ARP rod bolts that needed to have the rods resized, ARP head bolts, new Lunati cam, the right valve springs/retainers/locks, forged pistons, on and on. One thing led to another, and my cheap build motor isn't so cheap anymore!
