I think most of you are right, Salmon is right , yes they all 'tend' to run hot , Sixstarved is right , they should not using all the factory parts...problem is lots of years have gone by and some parts could be missing...usually its the easy stuff that gets overlooked...rather than worry about heads, thermostats, timing ,radiators etc, ( unless missing thermostat = water runs thru too fast , no time to cool, clogged radiators, timing way off etc),you need to see that the 'fillers' are all there and in correctly...my X fillers made a direct change of about 15-20F , and later I found the missing masticated filler mnissing on one side , it changed anoter 5-10F...when I bought the car in Ft Worth , driving it back in august it ran 210-220 (uphills at 230)doing 80+- mph...now it runs 175-185 , 195-200 in really tight traffic, stop n go, this is only w/ adding in the missing pieces...

also make sure the air baffle under is there..
