yes you could get automatic or manual trannys.
The manufacture requires a 180 degree thermostat. If your fan clutch is operating normally and the radiator has good flow it will probably be around 190 to 205. It may run a little cooler when the car is moving.
If it is still stock, expect no more than low to mid teens overall
I have a 94' z28 sitting on 20" d'vinci havoc Black. It all depends on the tire size... my tire size are 245/35/20 and they really close to touching.
yes. that is one of several blocks used for the 302.
The fan clutch may be at fault or if the fan shroud is damaged or missing may cause those syptoms.
