radiator is the stock harrison 3 core, fan is the stock 8 blade a/c fan 13.5inches in diameter with hd thermostat clutch, the shroud is the factory shroud for an a/c small block car. all the parts are for a 68 impala with a 327, a/c and a powerglide. all the cooling parts are less then a year old from being fresh. some less then a week. i have a 350, 700r4 overdrive, and a/c. far as i can tell, all the parts should be more then adequate. i have not checked the heater core, it works great, throws heat as it should in cold weather, and seems to flow water well. i will bypass it and see if it changes anything. im ready to try anything at this point.

i was kind of hoping someone somewhere had this issue before and could tell me one of those believe it or not stories that would solve everything. kind of like when i was told to add washers to lower the hood on my truck...lol
