Okay people, I have a 88 camaro with a 83 305/ 700r4(original). It has a edelbrock cam, pushrods and lifters. Edelbrock intake and carb. The heads have been ported and polished to match the rest of the setup and the usual stuff(water pump, radiator, thermostat180, electric fan 2950cfm) have also been replaced. Oh ya and headers too.
The car warms up to about 185-190 when I first start driving. When I go up any hills the car begins to heat-up to about 220-230. If I get on the pedal(not on hill) the car heats-up just the same. But when I idle the car will begin to cool back down. Because of this I've had to keep the car under 65 and I can't go on long trips. The problem with that is that I commute 70 miles to school, one way. If I continue to drive , it continues to heat-up!
Guys please help me. I can't figure this out but I'm confident it isn't much. This engine is the first engine I've ever built-up and I've done it on my own. I've had to ask many questions on the way but I got it going. This problem however is the only thing holding it back. Thanks... the timing is at 14 degrees which is what the cam card said to put it at,14-16. If I go below this it will bog, but I can go up with no pinging.

 

70 miles ,, wow
is the air dam intact?? (the piece of rubber under car that deflects air into the fans??)
