OK I have a camaro i recently put a 350 in but heres the problem im having a over heating problem with it, its been bored .60 over, i just bought a griffin radiator for it and have a electric fan that puts out 2100 cfm and a 160 deg thermostat and just a regular stock water pump i have all the air dams on the car and the timing isnt too advance to hurt anything the only thing im turning to is maybe my head gaskets are blown? is this a possibilitly.

now there is one more problem, My car wont charge up i have a good body to enigne ground and everything i think is hooked up right, the altenator was tested and it came back fine and the battery was tested and came back fine, but heres the thing i bought a aftermarket tach and somtimes when im drivng my old stock tach will kick on and the volts will go up and it will start charging, any idea what could be causeing this?

 

Are you relying on the factory "temperature guage" for the coolant indication?

 

As for it being a head gasket, do you have white smoke pouring out the tailpipes? or lots of air in the rad? if no then its not headgasket.

For the alternator, sounds like somthing in wiring. What type of alt is it? is it just a single wire alt?

 

Well i noticed today on my camaro i was running it with the hood off and noticed with the hood on it ran about 10 deg cooler as for the alt it has like 3 wires going to two which i dont know and 1 i think is going to the battery ill have to look at it to make sure.
