Customer Engines » Hibberts, Charles

Starting from the top this engine is already looking like a real beast with its Fast XFI-2.0 and our Butler Performance tall valve covers. These valve covers have also been fitted with only an evac pump bung and bolt on oil fill so it has that perfect amount of contrast- no valve cover breathers required with our Bp/GZ crankcase vacuum pump kit (includes our BP custom mount kit for use with the Serpentine system). We used our custom BP-Edelbrock/FAST XFI multi-port fuel injection system with full data logging capabilities. This should be perfect for Charles' 1976 Firebird which will be street driven but also used in road course and auto cross events. This customer also decided on a set of Edelbrock 87cc Round Port heads because of the many benefits aluminum heads can provide- including higher airflow, less weight and better cooling. Under the heads sit a set of our Butler/Ross 4.211" bore Flat top pistons with Eagle H-Beam rods connecting to the Eagle Specialty Products 455 x 4.250 stroke Forged crank. On the front of this engine is a March Sport Track serpentine system W/Power steering. All of this made this engine come together and produce 600 Ft. Lbs. Torque and 556 Horse Power while still an engine that will cruise down the highway and melt the tires at the same time. All that being said this builds core was a 455 block the customer purchased from us and by the time we were finished had 474 Cubic Inches of displacement.
