Default Re: My 69 L89 at Barrett jackson, lot # 1069

I've restored several original 69 l89 Corvettes. What I found is that if the car heats up with the aluminum heads it loses close to 75 horsepower. When the car is just at perfect operating temperature you can get one or two good rips through the gears and then it feels like somebody took the two end carbs off
