MAN IF ONLY MAKES 1050 HP I'M RECYCLING IT! I HAVE QUITE A BIT OF EXPERIENCE WITH THE SMALL BLOCK FORDS, WE MADE 947 HP WITH A 423 CUBIC INCH MOTOR - SURELY THIS THING WILL MAKE 1120 OR SO.
I highly doubt that a 428 small block makes 947 HP if NA with one 4 barrel unless you spin it near 10,000 / 11,000 RPM.

I have been wrong before however, I just don't see it this time.

SMALL BLOCK

YOUR DEFINATELY BEHIEND THE TIMES IF YOU HAVE NOT SEEN A SMALL BLOCK FORD MAKE 900+ HP, THERES BEEN A FEW OVER 1000 HP. THE SMALL BLOCK HEADS WE USE FLOW PRETTY CLOSE TO THE A HEAD WITH A MUCH SMALLER PORT - I'M LOOKING FOR THE TQ NOW WITH THE BIG BLOCK ALTHOUGH IT'S A FAIRLY SHORT STROKE.

950 horsepower would require more than 550 lb/ft of torque up at 9,000 RPM or, more than 665 lb/ft of torque at 7,500 RPM.

Not peak torque but, torque up at that RPM ... that is the simple math and that is what it would take.

EDIT: If your single 4 barrel, NA small block gets there ... then that's great.
