My '68 Camaro has still been running hot, has a 383 stroker engine (the one with a hairline crack that I wrote about on an earlier post). We've been trying to figure out why it has been running so hot, and if that may have caused the crack. I switched to a 160 degree thermostat (from 180), still runs hot. After driving a few miles, the upper radiator hose is hot, but the lower hose is only a little warm-- could this mean the problem might be in the radiator itself?
