Mustang overheating

82Mustang · 2005-06-27T04:36:02+00:00

I just rebuilt my 302 with new bearings, rings, fuel, oil, waterpumps, thermostat, cam, lifters, put a set of 289 hipo heads withstainless steel valves, edelbrock RPM series intake and Holley 600cfmcarb. Got the engine back in the car and fired it up and broke in thecam. The engine temp (100% water at that time) was normal. Chang thefluid to 50/50 mix and its still all good. Since then valves andtiming was tuned in but now the trouble starts. I start the car upbecasue there was a leak from the automatic transmision to check andadd fluid as neccesary. After checking fluids i look at the emp guageand its pushing for "H" so i shut the car off and ponder. :? comeback to the car the next day and start it and it still overheats. I goout and buy a new sending unit thinking mabey it went bad. nodifference. the water pump and thermostat are new and everythingseemed to work for a week but now??? Did i get a bad thermostat, waterpump, or did my stock radiator finally kick the bucket? or my fanclutch pass on? and i hope that the $500 i just dropped on valves,springs and head cleanup wasn?t for not. or that i have a crackedblock. any suggestions and/or tests that i can run would be greatlyappreciated.
