Disappointing ET's with 408

Here's an idea,rather then throw all of these different parts at it and continue to waste money going to the track where the weather conditions are different each time,why don't you do what you should have done before you installed the engine,DYNO THE ENGINE. You will WASTE more time and money screwing around with diferent parts and trips back and forth to the track then you would if you dyno the engine.You guys failed to notice that the 60' is horrible on that car.I think the intake was the wrong choice,the torque converter may also be a problem,you have to upgrade the fuel pump,did you change the valve springs to match the cam ? The spring on the Edelbrocks are not strong enough for a roller cam.Is this a solid or hydraulic roller ?If you do not want to take the engine out and dyno it then you should try to find a chassis dyno.Which ever you do you should bring different things to try,if you are bringing carbs make sure they are cleaned and in good working order.On the street you will not need any more then the 600,yes the larger carbs may make more power on the dyno but the Edelbrocks make more torque and are more responsive for the street.
