I think the blower will help get you to your goals pretty easy. I had a .030 over 454 with iron heads and a Blower Shop 250 blower. With 8 to 1 compression it made 550 horsepower at 8 pounds of boost and no intercooler, all with a flat tappet cam. It ran that way for 14 years. This year after the motor ate an exhaust valve seat, I have decided to rebuild it with aluminum heads and bigger cam. Shooting for the 650 horsepower range. Good luck with your 454 build.

Those are new Sealed Sower 0.030" forged pistons. The engine has been refreshed at one time. They are the Sealed Power replacement for the TRW stock pistons. They should be good for a mild blower application. I wouldn't worry about cleaning the tops of the pistons. Just get the tune right.
