I`ve thought this all along and we talked about things before and after I did the carb then he sells it.............

Fuel delivery based on what op told me was questionable but he swore it was good...........I thought you said you were going in a different direction like late model efi stuff at least that`s what I remember you saying.........
I spoke with the OP also about the valvetrain. There is no reason a 440 inch motor, with EZ heads and a large roller cam, should be shifted at 6500 and slow down if shifted higher. If the numbers look good in the 1/8th, but it doesn't carry them in the 1/4, then the motor is laying down. And now, with a new cam and new springs, the argument that the springs are weak doesn't seem logical. I still say the geometry is off substantially.
