If it makes you feel any better...
Look at my gallery) That 428 ran for about 30min. then the cam went flat. A few of the lobes were rounded. I think maybe I did not keep the rpm,s up enuff? Maybe air pocket in the intake causing the topend to get hot? may mis adjusted valve lash. But needless to say the bottom end of the motor was trash. I got over it and decided to buy a new csx block and have Gessford build it. Plus I had a rear seal
oil leak.
