"HIGH OCTANE" Jeep 4.6 Stroker Engine Package
For those who want the stoutest most reliable street Jeep stroker available on the market that still retains factory manners and dependability as long as you don't mind running premium octane fuel hence the name "HIGH OCTANE" then this one fits the bill. We have done our research and developed an elite engine package that utilizes our custom made hypereutectic pistons and lightweight rings with the highly desired 6.125" (Long)rods, 10.5:1 compression with our newest designed competition head for this piston design. You may ask why Hypereutectic pistons and not forged? For a naturally aspirated engine that see's daily driving and hot rodding in all types of weather you can not beat a well designed Hypereutectic for quiet operation, excellent long life, anti-scuffing and sealing ability. To this point there has not been a hypereutectic option with a 6.125"(Long) rod option so we made one and created a new animal. From the factory the original 4.2(258) started life around 100hp to eventually topping out around 190hp by the 4.0(242). "HIGH OCTANE" at 4.6 liters is another animal all together, on our dyno this package pumped out 366hp and 373ftlbs of torque with one of our less aggressive cams. With this package we can custom tailor the cam to suite your needs and bring the power in where you want it. This package will have all of our goodies such as: 1.7 adjustable roller rockers, 3/8" pushrods, billet valve cover spacer kit w/billet valve cover perimeter retainers, billet thermostat housing, ATI serpentine damper kit, slicked out paint color of your choice, intake block-off plate, water pump, copper intake/exhaust manifold gasket, stainless steel winged washer kit, 24lb injectors. Recommendations: Intake/Intake/Intake did we say Intake, to totally utilize this package we recommend an extremely ported stock intake manifold or custom setup(Sheetmetal) with an oversized throttle body(These are not mandatory items just recommended), header with 3" collector and a custom tune is MANDATORY with 91 octane minimum. Manual transmissions require clutch upgrade such as Mcleod or Centerforce. Automatic transmissions say a prayer then prepare for a moment of silence unless built or shift kit(Except AW4's, if they are healthy they seem to hold up well).
