The 383 525HP engine package is ideal for the airboater that is looking to replace his current small block GM 350 engine. The 383 features a 3.750 stroke crankshaft where the 350 has a 3.480 stroke. By adding the .270 stroke to the classic 350 Chevy engine it creates unbelievable low to mid range torque. When you are building or looking at re-powering your airboat low to mid range torque is what you want. Running on dry ground takes a lot of torque and power to make it happen (We have done just that). We here at Proformance Unlimited have tested many different engine combinations perfecting the perfect balance of torque and power to allow you to get the most out of your airboating experience. Designing this type of extreme duty engine goes well past just making good power and torque. We have developed several combinations that are extremely durable and will allow the user to enjoy his or her airboating experience with limited down time and maintenance.
