Nothing could stop me from buying the 65 Mustand that was setting up for 20 years!!  Now, after $4,000. it is on the road but gets hot right away, in 15 - 20 minutes.  Car has new radiator(yes, from China), new 160 degree thermos, engine was flushed with water and garden hose.  Heater was clogged at first and reverse garden hose opened that up.  After engine is started and runnning a reasonable while (radiator cap off) the thermos opens and water is flowing left to right in the radiator and appears to be in ample amount.  I let ir idle for a while with cap off to let air out.  I drove the car a little when I first pourchased it but never noticed it getting hot??  I have Peaks radiator flush in it right now and plan to drive it as much as possible in the next few days.  Will I need to pull the heads or completely tear engine down and tank the block?  This is an original two barrell car that starts good, runs and accelerates good!  Thanks for your help.
