I have been given dozens of reasons for my overheating problem. None of which apply to this engine. Understand that I am pushing 400+ HP with a 10.5 to 1 compression ratio pistons with Vortec heads. The car has 72000 miles but the engine only has 3000 miles. The car is not equiped with any type of poluttion control. (I.E. Cataliytic converter, ERG valve, air pump, etc.) It is carborated with a free flow air filter with a new filter. I have had a number of local Hot Rod shops and muffler shops tell me otherwise than what I am am being told in this forum. I am only trying to conferm the correct answer for my problem.
I repeate, the cooling system circulation has no problems. No vapor locks, No air bubbles, high volume aluminum water pump, NO THERMOSTAT, No bent or crushed exhaust. The ehaust system is only 2 years old but only a 2 inch which was stoke at 195 HP. The L82 Vette had about 40-50 more HP stoke and it had a 2 1/2 inch exhaust.
Who has the right answer?
The local shops around me or you at this forum.
