well i installed the high volume pump and the 180 degree high flow stat and had the radiator flushed again just for good measure, and the results are in..... it runs great up and down the road all day long never gets above 180. but basiclly the same as before, if i stop and let it idle while my wife runs into the store for 10 minutes it gradually warms up. just in 10 minutes it was already holding 200 degrees and its only 85 degrees outside. mechaniclly the engine is sound, i dont know how many miles are on it exactly since it was rebuilt, but its somewhere around 30K to 40K, and probably 10 years old. it has a factory 3 row V8 radiator, a soild factory 7 blade fan, a factory shroud, im running the timming at 12 BTC on a efi swap, the engine is bored .30 over but that shouldnt make it run hot. i donk know but in my experience i should be able to let it idle all day long without any over temp problems, right? i guess the next thing to do, well about the only thing left is to put a 4 row radiator in it but it will probably be a while for that. or maybe somebody out there knows something else or sees something im doing wrong or cold do better.
