The "300HP" is our entry level engine package and they normally make between 290-320hp/320-340tq with an excellent power band from idle to redline. All of our engine packages are custom hand built to spec, work well both Fuel injected or Carbureted. These engines are all upgradable with additional available options from below.
*Recommendations for upgrades- Walbro 255 fuel pump, 24-36lb injectors, upgraded header w/2.5" collector and exhaust minimum!, intake porting, bigger throttle body, upgraded radiator, upgraded motor mounts(Drivers side mount that bolts on the block MUST have increased bolt count over the factory three bolts to keep from breaking block from added power, passenger can stay stock), cold air intake and last once everything is upgraded have it properly custom tuned then everything and everyone is happy. Every motor is dynoed with a video and power numbers, 12 month/12,000 mile warranty and complimentary Newcomer racing T or Sweat shirt w/hat. All engines will be shipped bare unless our custom high quality monotone paint option is applied from the options list.
