455 Block bored 30 over to achieve 619 HP and 613 torque. We achieved this feat using Ross/Butler custom Flat top Forged Pistons that we stock along with Scat H-Beam rods with a ARP rod bolt upgrade. Also with this assembly was a Scat forged 4.250 stoke crank and Johnson Hydraulic lifters made right here in America. We installed a COMP/BP custom billet hydraulic roller cam with 112 lobe separation and to make sure we kept the oil pressure up we used a BP 80 PSI PRO oil pump. This customer went with a set of Scorpion 1.65 ratio Rockers we also bolted on a Canton 15-452 road race/drag race oil pan that holds an extra quart of oil compared to stock. To help keep everything in balance we used a BHJ SFI approved 4 bolt damper and a Hays SFI Flexplate. This build was topped off with a Fast EZ EFI 2.0 throttle body and BP/EDL Custom built 87cc Rd Port 340+CFM Heads. This is a Pump gas engine bound for a 1966 GTO and we believe it will get a lot of use through the years to come.
