Product Description

This is a motor package that was designed to fill the gap between the 760 big bore and the billet stroker in both cost and performance. Using our custom designed big bore 850 Sleeves we are able to offer this package affordably with the ability to run many configurations of our Blowsion billet head and dome combinations. For added durability, we reinforce all of our 850 stroker motors with our Blowsion billet Case Cranker reinforcement plate. The resulting cases are far stronger than stock and are ready to accept whatever horsepower abuse that is thrown at them. (Please note that if a stock stroke crank is used than no trenching and Case Cranker reinforcing is required). All porting in both cylinders and cases is done with a CNC machine and hand finished to attain the highest standards. This gives us the ability to make calculated and interpretive changes for each customer’s performance demands. Call or Email for further details and costs as the options are broad.
